Description

Technical Field

[0001] The utility model relates to the technical field of elevator installation, in particular to a quick-installation steel structure counterweight frame fixing structure. Background Technique

[0002] The counterweight is a component of the elevator traction system. The counterweight is located on the other side of the car. There is a traction rope connecting between the car and the counterweight frame. The traction rope drives the car to move up and down by the friction force generated by the traction wheel on the roof. The function of the counterweight is to balance the weight of the car. In this way, the traction wheel only needs to drive the difference between the weight of the car and the counterweight to make the car move up and down.

[0003] At present, in the quick-installation steel structure elevator, when installing the counterweight frame, it is necessary to fix the counterweight frame. In the existing technology, usually long wooden squares are used to support the counterweight frame in the pit for fixing, and then the next installation is carried out. The stability is poor, and the counterweight frame is transported to the on-site installation place in bulk, and it is easy to be bumped and damaged during the transportation process. Summary of the Invention

[0004] The utility model aims to solve the deficiencies of the existing technology and provides a quick-installation steel structure counterweight frame fixing structure.

[0005] To achieve the above object, the utility model adopts the following technical solutions: A quick-installation steel structure counterweight frame fixing structure includes a counterweight frame body, and also includes a pair of upper brackets and a pair of lower brackets. The upper brackets are U-shaped, and the lower brackets are L-shaped. The top of the counterweight frame body is fixed on a cross beam of the steel structure hoistway through the upper brackets, and the bottom of the counterweight frame body is fixed on another cross beam of the steel structure hoistway through the lower brackets. And the guide shoes on the outer sides of the two side frames of the counterweight frame body are sleeved on the counterweight guide rails.

[0006] Specifically, two pairs of first mounting holes are provided at both ends of the inner bottom of the upper brackets. Corresponding second mounting holes are provided at the top of the upper frame of the counterweight frame body and the top of the corresponding cross beam. The upper brackets are fixed by screwing bolts into the first mounting holes and the second mounting holes.

[0007] Specifically, the first mounting holes are strip-shaped holes, and the second mounting holes are circular threaded holes.

[0008] Specifically, a pair of third mounting holes are provided at the ends of the vertical part and the horizontal part of the lower brackets. Corresponding fourth mounting holes are provided at the outer side of the lower frame of the counterweight frame body and the top of the corresponding cross beam. The lower brackets are fixed by screwing bolts into the third mounting holes and the fourth mounting holes.

[0009] Specifically, the third mounting holes are strip-shaped holes, and the fourth mounting holes are circular threaded holes.

[0010] The beneficial effects of the present utility model are as follows: The present utility model is applicable to the counterweight frame installation and fixation module in a quick-installable steel structure elevator. The counterweight frame is temporarily fixed and installed on the steel structure crossbeam through two groups of upper brackets and two groups of lower brackets, so that the counterweight frame can be directly pre-installed in the steel structure hoistway and transported to the construction site for assembly together, which can save the on-site installation time, and the installation is firm and reliable, avoiding damage problems during transportation. The subsequent disassembly operation is fast, and it is flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be described in detail with reference to the embodiments of the present utility model and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present utility model will be further described below with reference to the accompanying drawings and embodiments:

[0017] As Figures 1 - 3 shown, a quick-installable steel structure counterweight frame fixing structure includes a counterweight frame body 1, and also includes a pair of upper brackets 2 and a pair of lower brackets 3. The upper bracket 2 is U-shaped, and the lower bracket 3 is L-shaped. The top of the counterweight frame body 1 is fixed on a crossbeam 4 of the steel structure hoistway through the upper bracket 2, and the bottom of the counterweight frame body 1 is fixed on another crossbeam 4 of the steel structure hoistway through the lower bracket 3. Moreover, the guide shoes 5 on the outer sides of the two side frames of the counterweight frame body 1 are sleeved on the counterweight guide rails 6.

[0018] At both ends of the inner bottom of the upper bracket 2, there are two pairs of first installation holes 7. On the top of the upper frame of the counterweight frame body 1 and the top of the corresponding crossbeam 4, there are second installation holes corresponding to the first installation holes 7. The upper bracket 2 is fixed by screwing bolts into the first installation holes and the second installation holes; the first installation holes 7 are strip-shaped holes, and the second installation holes are circular threaded holes. The setting of the strip-shaped holes can appropriately adjust the installation position of the upper bracket 2.

[0019] A pair of third mounting holes 8 are provided at both the vertical part and the end of the horizontal part of the lower bracket 3. Corresponding fourth mounting holes are provided on the outer side of the lower border of the counterweight frame body 1 and the top of the corresponding cross beam 4. The lower bracket 3 is fixed by screwing bolts into the third mounting holes 8 and the fourth mounting holes. The third mounting holes 8 are strip-shaped holes, and the fourth mounting holes are circular threaded holes. The setting of the strip-shaped holes can appropriately adjust the installation position of the lower bracket 3.

[0020] This counterweight frame fixing structure is applicable to the counterweight frame installation and fixing module in a quick-assembly steel structure elevator. In a quick-assembly steel structure, the counterweight frame needs to be pre-assembled in the factory and then transported to the construction site for assembly together with the steel structure hoistway. Using the upper bracket 2 and the lower bracket 3, the counterweight frame can be quickly fixed, which can save the on-site installation time. After the counterweight frame does not need to be fixed, the upper bracket 2 and the lower bracket 3 can be directly removed. The structure of the present utility model is simple, firm and reliable, and is convenient for disassembly.
