The utility model relates to a simple detachable portal frame, which is characterized in that the simple detachable portal frame comprises a transverse beam, a tackle is sheathed on the transverse beam, pulleys are respectively arranged at the two ends of the transverse beam, the two ends of the transverse beam are respectively connected with stand columns, bases are arranged at the bottoms of the stand columns, universal wheels are installed at the bottoms of the bases, the two sides of the stand columns are respectively connected with supporting pieces and the bottoms of the supporting pieces are fixed on the bases. Since all parts of the simple detachable portal frame are prefabricated parts, the parts can be assembled in the field during use; since the parts are connected with each other by using bolts and pins, the difficulty in transportation and field assembling can be minimized; since the weight of the parts except the transverse beam and the stand columns is light, the labor intensity of field assembling is low and the field assembling can be completed by several people; and since the tackle and the universal wheels are arranged, the portal frame is more flexible to use, construction period is shortened, material costs are reduced, safety and flexibility are increased and the labor intensity of construction personnel is reduced.
Description
Technical field
The utility model relates to a kind of simple and easy detachable portal frame, the hoisting operation instrument that uses in the installation exercise of the midget plant that particularly a kind of weight is lighter and the checking maintenance process.
Background technology
At present, when chemical plant installations construction and checking maintenance operation, in the middle of hoisting operation, run into some extraordinary circumstances through regular meeting, as:
1, installation or replacing are positioned at the apparatus platform below such as equipment such as pump, motor, little heat exchangers.
Can't directly use crane during construction, can only equipment be winched on the platform by crane, by jack equipment is in place then, labor strength is big, the effort of taking a lot of work.
Though 2, erecting equipment weight is light but quantity is more and the position is special.
Can directly use crane during installation but since the special need in position lift with large-scale crane, this kind method convenient power-saving, but that large-scale crane machine-team takes is higher, construction cost is too big.
3, erecting equipment is positioned at factory building inside, in the factory building no purlin car can with and the factory building top do not allow to hole.
Can only hang jack this moment at the inner suspension centre of seeking of factory building, and hoisting point position is improper will to bring very big inconvenience to construction.
Can use portal frame to carry out equipment when the above-mentioned situation of reply installs or has bad luck.And there are a lot of deficiencies in traditional portal frame:
(1) portal frame is in a single day prefabricated finishes lifting altitude and span just is determined, and limitation is bigger during use.
(2) the traditional dragon door frame generally adopts the form of welding that steel pipe or shaped steel are connected to form, if often face the super wide problem of superelevation when span or height are big when prefabricated end transports the scene to, to having relatively high expectations of transport vehicle.Will increase the site operation amount if weld at the scene, and the scene is often limited in the checking maintenance operation.
(3) portal frame can only use at the three unities after arriving the use scene, is not suitable for long distance and cuts to, and the cost problem of often considering to transport when use in another distance next time place far away is and prefabricated again, and recycling rate of waterused is extremely low, has caused the serious wasting of resources.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of above-mentioned defective that solved is provided, has shortened construction period, increased the simple and easy detachable portal frame of safety and alerting ability.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of simple and easy detachable portal frame, it is characterized in that: comprise crossbeam, be with coaster on the crossbeam, the two ends of crossbeam are respectively equipped with pulley, the two ends of crossbeam also are connected with column respectively, and the bottom of column is provided with base, and the bottom of base is equipped with cardan wheel, the both sides of column are connected with strut member respectively, and the bottom of strut member is fixed on the base.
Described crossbeam adopts I-beam section, and column adopts the H steel, and strut member adopts steel pipe, and base adopts channel-section steel.Also can adopt the enough and lighter material of weight of other intensity.
Simple and easy detachable portal frame structure all is a preformed part, assembled on site gets final product in use, parts use bolt each other, bearing pin connects, can reduce transportation and field-installed difficulty to the full extent, other component weight is lighter except that crossbeam and column, assembled on site intensity is lower, several people just can finish, coaster and cardan wheel are set, use more flexibly, can whether use cardan wheel according to the decision of the size of hoisting capacity, load-carrying ability significantly promotes, adaptive capacity is strong, connect easyly, can make the column and the crossbeam of different size, determine span and height according to field condition during use, and then select suitable components to make up, after being damaged, the somewhere parts also can in time repair or replace.
During use, earlier with each transported in parts of the utility model portal frame to making use, and assemble, assemble method is: coaster is enclosed within on the crossbeam, and the coaster slide fastener is put into the groove of the pulley at crossbeam two ends, and jack is hung on the coaster; Crossbeam and column are passed through bolted connection, and bolt up is installed to cardan wheel on the base, and strut member is connected with bearing pin with base, subsequently crossbeam and column is sling, and base is connected with column, and last bolt up is connected strut member with column.
After assembling is finished, simple and easy detachable portal frame is moved to the use location, by coaster slide fastener control coaster position, by jack control lifting altitude by the cardan wheel on the base; Move by coaster or cardan wheel after equipment hoists,, need behind good position, portal frame station, cardan wheel is laid down, only carry out short range and move by coaster if hoisting capacity is bigger.
After finishing using, can disassemble according to reverse order, reusable.
The beneficial effect that the utility model had is: simple and easy detachable portal frame structure all is a preformed part, assembled on site gets final product in use, parts use bolt each other, bearing pin connects, can reduce transportation and field-installed difficulty to the full extent, other component weight is lighter except that crossbeam and column, assembled on site intensity is lower, several people just can finish, coaster and cardan wheel are set, use more flexibly, can whether use cardan wheel according to the decision of the size of hoisting capacity, load-carrying ability significantly promotes, adaptive capacity is strong, connect easyly, can make the column and the crossbeam of different size, determine span and height according to field condition during use, and then select suitable components to make up, also can in time repair or replace after the somewhere parts are damaged, shorten construction period, reduce the materials cost, increase safety and alerting ability, and reduced the construction operation personnel labor intensity.
