Embodiment 1

[0037] An attached lifting and transporting device for demolishing concrete support beams, including a trolley system and a lifting system, see figure 1 , the trolley system includes a trolley 101 arranged on the running track 6, and the trolley 101 is set as a structure including upper and lower layers of "mesh"-shaped frames, and the "mesh"-shaped frames are all composed of beam connections, and the upper 1. The "mesh"-shaped frames on the lower two floors are all connected by vertical connecting beams at the four corners; see figure 2 , the middle part of the "mesh"-shaped frame of the upper layer is connected with the upper steel plate on the two vertical connecting beams perpendicular to the direction of the running track 6, and the two ends of the upper steel plate are respectively symmetrically provided with two rows of first bolt holes, each The number of the first bolt holes in each row is at least two, and they are evenly distributed. The four cantilever beams 2 are...

Embodiment 2

[0043] An attached lifting and transportation device for removing concrete support beams. On the basis of Embodiment 1, further, the two sides of the trolley system are respectively provided with support removal devices 17, and the support removal devices 17 are provided with concrete support beams. Block 16, the two ends of the concrete support beam block 16 are provided with reserved hoisting holes.

[0044] Furthermore, the ends of the hoisting rope 15 and the external force pulling rope 7 are respectively provided with matching locks.

[0045] Furthermore, the cantilever beam 2 is formed by welding one beam steel plate and two beam steel bars.

[0046] Furthermore, two rows of second bolt holes are provided on the beam steel plate, and the number of the second bolt holes in each row is at least two, and the number of the second bolt holes is evenly distributed.

[0047] Furthermore, the four cantilever beams 2 are evenly distributed into two groups, and are symmetrically ...

Embodiment 3

[0050] Embodiment 1 or embodiment 2 described attached demolition concrete support beams use the method of lifting, transportation device, comprise the following steps,

[0051] The first step is to lay and fix the running track 6 according to the needs of the scope of work;

[0052] In the second step, the trolley 101 is installed on the running track 6, and the suspension distance of the cantilever beam 2 is adjusted by adjusting the bolts of the cantilever beam 2 according to the maximum load of lifting;

[0053] The third step is to select the counterweight 4 according to the maximum lifting load, and place the counterweight 4 on the counterweight pallet 3;

[0054] In the fourth step, the hoisting rope 15 and the external force traction rope 7 are drawn out from the hoisting hoist 10 and the traction hoist 12 respectively, and are extended downward through the guide wheel 5 on the hoisting side;

[0055] In the fifth step, the trolley 101 moves to the top of the lifting ...

Abstract

The invention discloses an attached hoisting and transporting device for dismantling concrete supporting beams and a using method of the attached hoisting and transporting device. The hoisting and transporting device comprises a trolley system and a hosting system, the trolley system comprises a trolley arranged on operation tracks, the trolley comprises an upper-layer frame structure shaped likethe Chinese character 'mu' and a lower-layer frame structure shaped like the Chinese character 'mu', a balance weight tray is arranged on a lower steel plate and connected with a balance weight adjusting rope which is connected with a balance weight adjusting winch, and a self-powered speed limiting braking device is mounted on a pulley block; and rack winches having the same power and operating synchronously are fixed to the middles of operation tracks at the two side edges of a foundation pit correspondingly, and the balance weight adjusting winch, a cantilever beam, the rack winches and twolifting winches constitute the hoisting system, wherein the two lifting winches have the same power and operate synchronously. The problems of multi-layer form dismantling and hoisting of the supporting beams in the vertical direction are effectively solved, the attached hoisting and transporting device can be used for dismantling, hoisting and transporting of the oversized and large-section concrete supporting beams, the pressure of hoisting operation is relieved, and the construction progress is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an attached lifting and transporting device for demolishing concrete support beams and a use method. Background technique [0002] Most deep foundation pits are designed in the form of concrete support beams. However, in the construction of super-large deep foundation pits and large-section concrete support beams, the previous lifting machinery such as tower cranes cannot meet the construction requirements. , The transportation method has the following disadvantages: ①The dismantling of super-large deep foundation pits and super-large cross-section support beams will cause secondary transportation after the demolition of concrete support beams due to the limited radius of existing mechanical operations and the limitation of lifting load at the end. Increase labor and machinery costs. Therefore it is conceived to provide a lifting and transportation devi...
