Description

Technical Field

[0001] This utility model relates to the field of building installation engineering technology, and in particular to a purlin installation device. Background Technology

[0002] Currently, the common practice for installing wall purlins during building structure installation is as follows: the wall purlins are hoisted to the installation position by ropes using pulleys attached to the beams, and then the wall purlins are secured to the column purlin support plates by hand by people on both sides of the column purlin support plates. Finally, the hoisting rope locks are released manually.

[0003] The above procedures have the following drawbacks: First, only one wall purlin can be installed at a time, resulting in slow installation speed and low work efficiency; second, all operations are manual, requiring multiple people to cooperate and coordinate, which increases labor costs and construction costs; and third, single-piece transportation is cumbersome, involves high manual labor intensity, and poses safety hazards. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the present invention provides a purlin installation device.

[0005] The purlin installation device provided by this utility model adopts the following technical solution:

[0006] A purlin installation device includes at least two vertically suspended uprights, with a suspension rope connected to the top of each upright. A connecting rod is connected between the uprights. A slide rail is vertically fixed to the surface of each upright. Multiple limiting holes are vertically formed on the surface of the slide rail. A bracket for supporting the purlin is slidably installed on the slide rail. The bracket includes a limiting mechanism for positioning. The limiting mechanism includes a limiting rod that can be detachably slidably passed through the limiting hole.

[0007] By adopting the above technical solution, brackets of different numbers or positions can be installed on each slide rail. Positioned by limit rods, the purlin installation device can hoist multiple purlins at the same time, which has a good purlin fixing effect, improves the stability, installability and convenience of purlin installation, saves construction workers more time and effort, and significantly reduces construction costs.

[0008] Optionally, the bracket includes a vertically arranged back plate, a bottom plate is vertically fixed to the bottom end of the back plate, a front plate is vertically fixed to the end of the bottom plate away from the back plate, the back plate is slidably connected to the slide rail, and a limiting rod is slidably inserted through the back plate and the limiting hole.

[0009] By adopting the above technical solution, the back panel, bottom panel, and front panel form a space to accommodate the purlins for ease of use.

[0010] Optionally, the limiting mechanism also includes a fixed plate that is parallel to the back plate and fixedly installed. The fixed plate is located above the bottom plate. The limiting rod slides through the fixed plate. A support plate is sleeved and fixedly connected to the limiting rod. The support plate is located between the back plate and the fixed plate. A compression spring is also sleeved on the limiting rod. The compression spring elastically supports the support plate and the fixed plate.

[0011] By adopting the above technical solution, the limiting rod is elastically driven by a compression spring and inserted into the limiting hole, making the limiting rod more stable during operation.

[0012] Optionally, a positioning seat is fixed to each of the two sides of the top surface of the base plate, and a limiting mechanism is located between the two positioning seats. The positioning seats, the base plate, and the front plate form a space for accommodating the purlin.

[0013] By adopting the above technical solution, a space is formed between the two positioning seats to accommodate the limiting mechanism, so that construction personnel can operate the limiting mechanism.

[0014] Optionally, one of the positioning seats has a movable top plate rotatably connected to its top surface to prevent the purlin from moving upward.

[0015] By adopting the above technical solution, the movable top plate can be rotated above the purlin to block the purlin and improve the stability during the purlin hoisting process.

[0016] Optionally, the slide rail has a hollow structure, with a limiting plate fixed above each limiting hole position inside the slide rail, and the limiting rod making movable contact with the bottom surface of the limiting plate.

[0017] By adopting the above technical solution, when the limiting rod is inserted into the limiting hole, the top surface of the limiting rod can contact the bottom surface of the limiting plate, and the limiting plate supports the limiting rod to improve the stability of the limiting rod after insertion.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 The present invention will be described in further detail below.

[0024] This utility model discloses a purlin installation device. (Refer to...) Figure 1 The purlin installation device includes two vertically suspended uprights 1. In this embodiment, the uprights 1 are H-shaped steels. The top of the uprights 1 is connected to a lifting rope 10, which can be lifted by a crane. Multiple connecting rods 11 are fixed between the two uprights 1, so that the two uprights 1 and the multiple connecting rods 11 form a whole.

[0025] Reference Figure 1 and Figure 2 A slide rail 2 is vertically fixed to the web of the upright 1. In this embodiment, the slide rail 2 has a T-shaped cross-section and is hollow. Multiple limiting holes 20 are evenly opened vertically on the surface of the slide rail 2. Several brackets 3 for supporting purlins are slidably installed on the slide rail 2. The brackets 3 include a vertically arranged back plate 30. Two fixing hooks 31 for hooking the slide rail 2 are fixed to the side of the back plate 30 near the slide rail 2. The fixing hooks 31 are generally L-shaped. A bottom plate 32 is vertically fixed to the side of the back plate 30 away from the slide rail 2. A rib plate 320 for vertically supporting the bottom plate 32 is fixed between the bottom surface of the bottom plate 32 and the back plate 30.

[0026] Reference Figure 2 and Figure 3 A front plate 33 is vertically fixed to the end of the base plate 32 away from the back plate 30. Two positioning seats 34 are fixed to the side of the back plate 30 near the front plate 33. There is an operating space between the two positioning seats 34. The positioning seats 34, the base plate 32, and the front plate 33 form a space to accommodate the purlin. A movable top plate 35 is rotatably connected to the top surface of one of the positioning seats 34. The movable top plate 35 is used to restrict the upward movement of the purlin to improve the stability of the purlin during hoisting.

[0027] Reference Figure 2 and Figure 3A positioning shaft 350 is vertically fixed to the top surface of the positioning seat 34. One end of the movable top plate 35 is rotatably connected to the positioning shaft 350, and the other end of the movable top plate 35 is fixed to a lever 351. By moving the lever 351, the movable top plate 35 can be driven to rotate along the positioning shaft 350. A limiting mechanism 36 is installed on the back plate 30 to fix the bracket 3 in conjunction with the limiting hole 20. The limiting mechanism 36 is located between the two positioning seats 34. The limiting mechanism 36 includes a limiting rod 360 that slides through the back plate 30 and the limiting hole 20. A pull plate 361 is fixed to the end of the limiting rod 360 away from the slide rail 2.

[0028] Reference Figure 2 and Figure 3 A fixing plate 362 is fixed between the two positioning seats 34. A limiting rod 360 slides through the fixing plate 362. A support plate 363 is also fixedly fitted on the limiting rod 360. The support plate 363 is located between the back plate 30 and the fixing plate 362. A compression spring 364 is also fitted on the limiting rod 360. The compression spring 364 is elastically supported between the support plate 363 and the fixing plate 362. The compression spring 364 has an elastic tendency to drive the limiting rod 360 into the limiting hole 20.

[0029] Reference Figure 2 and Figure 3 Inside the slide rail 2, a limiting plate 21 is fixed above each limiting hole 20. When the limiting rod 360 is inserted into the limiting hole 20, the top surface of the limiting rod 360 can contact the bottom surface of the limiting plate 21, and the limiting plate 21 supports the limiting rod 360 to improve the stability of the limiting rod 360 after insertion.

[0030] The implementation principle of the purlin installation device in this embodiment is as follows: Construction personnel can install a corresponding number of brackets 3 on the slide rail 2 according to the required number of purlins to be hoisted. When the bracket 3 is fitted onto the slide rail 2, the pull plate 361 is pulled outwards. The pull plate 361 drives the limiting rod 360 to move outwards, thereby allowing the bracket 3 to move along the length of the slide rail 2. When the bracket 3 moves to the desired position, the pull plate 361 is released, and the compression spring 364 elastically extends, driving the limiting rod 360 to insert into the corresponding limiting hole 20, thereby fixing the bracket 3. This method allows for convenient adjustment of the position and number of brackets 3 installed.

[0031] The purlins are then placed sequentially on the paired brackets 3. The movable top plate 35 is rotated above the purlins using the lever 351. The upright 1 is then lifted using a crane and hoisting rope 10 until the purlin is in its installation position. Construction workers can then easily remove the purlin by reversing the movable top plate 35 for installation. This purlin installation device can simultaneously lift multiple purlins, providing excellent purlin fixation and improving the stability, ease of installation, and convenience of purlin installation. It saves construction workers time and effort, and significantly reduces construction costs.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
