Description

TECHNICAL FIELD

[0001] The utility model relates to construction device technical field especially relates to a ventilation pipeline construction device. BACKGROUND

[0002] In the ventilation pipeline construction, the wind pipe hoisting is an important content. The ventilation wind pipe has more size specifications, and the quantity is more;

[0003] Through the retrieval, the patent of a kind of clamp for hoisting wind pipe in the publication CN203865832U adopts upper and lower clamping plates, the upper and lower clamping plates are π type, the upper and lower clamping plates are fixed by screw rod, nut, gasket at both ends, but the following shortcomings are found in use:

[0004] 1. The device only supports vertical size adjustment in design, which limits its performance when facing diversified specifications of ventilation pipeline. In actual application, the diameter, shape and installation angle of ventilation pipeline often vary, and the device cannot adapt to these changes, greatly limiting its use range and efficiency;

[0005] 2. The gasket function of the current device is limited to providing clamping cushioning, which limits the application effect of the device in complex environments. In the ventilation system, the gasket not only needs to be cushioned, but also needs to be fixed again to ensure the stable operation and energy efficiency of the system.

[0006] Therefore, we propose a ventilation pipeline construction device. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims at solving the shortcomings that the device can only be vertically adjusted in size in prior art, and does not have universality when encountering ventilation pipelines of different specifications, and the gasket function of the device is single and can only play a buffering role, and proposes a ventilation pipeline construction device.

[0008] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0009] A ventilation pipeline construction device, comprising a plurality of bearing assemblies for installing ventilation pipelines, each bearing assembly comprising: two first positioning blocks, two elastic belts, four connecting rods, two second positioning blocks, four hollow bolts, four second bolts and a plurality of first bolts, the two second positioning blocks and the two first positioning blocks are crosswise arranged, the two first positioning blocks and the two second positioning blocks are provided with third positioning holes, the two sides of the two first positioning blocks are respectively provided with two second limiting holes, the ninety-degree corner positions of the two first positioning blocks are respectively provided with two grooves, and the two sides of the grooves are respectively provided with a plurality of second positioning holes.

[0010] Preferably, the elastic bands are further provided with hollow shafts fixedly connected to both ends, and four hollow bolts pass through the corresponding second positioning holes and the corresponding hollow shafts and are threadedly connected to the corresponding second bolts.

[0011] Preferably, each of the four connecting rods has a first positioning hole on both sides near its two ends.

[0012] Preferably, multiple first limiting holes are provided on both sides of the second positioning block, and a fourth positioning hole is provided on the top of both the upper second positioning block and the upper first positioning block; multiple first bolts pass through the corresponding first limiting holes and are fixedly connected to the corresponding first positioning holes.

[0013] The top of the second positioning block located on the upper side and the first positioning block located on the upper side are provided with a connecting component, the design of which ensures the stability of the device during construction;

[0014] The bottom of the second positioning block located on the lower side and the first positioning block located on the lower side are provided with anti-slip components, which ensure the stability of the device on the support surface.

[0015] Preferably, the connecting assembly includes two third bolts, which are respectively fixedly connected to the top of the upper second positioning block and the top of the upper first positioning block. The outer walls of the two third bolts are connected with positioning rings, and the positioning rings are fixedly connected with lifting lugs.

[0016] Preferably, the anti-slip component includes two pads, which are respectively fixedly connected to the bottom of the lower first positioning block and the bottom of the lower second positioning block.

[0017] In this application, during use, firstly, all the first bolts are unscrewed from the first positioning holes through the first limiting holes. Then, the two first positioning blocks and the two second positioning blocks are separated from the four connecting rods in sequence. Next, the two second bolts are unscrewed from the hollow bolts in sequence. The two ends of the two elastic bands are removed from the hollow bolts in sequence and separated. Here, the two first positioning blocks and the two second positioning blocks can be interchanged. First, any one of the first positioning blocks is placed on the ventilation duct. Then, the two connecting rods are inserted into the two third positioning holes in the ventilation duct. The operation is repeated in sequence. Then, the two elastic bands are placed on the ventilation duct in sequence.

[0018] In the slot of a first positioning block, first insert one hollow bolt into the second positioning hole, then put one end of the hollow shaft of one elastic band into the hollow bolt, and then insert the second bolt into the other side of the same hollow bolt and tighten it. Repeat this operation to fix the other end of the elastic band in the slot of another first positioning block. Repeat the operation to install the other elastic band on the other side as shown in the figure.

[0019] Simultaneously retract one of the first positioning blocks and one of the corresponding second positioning blocks using the connecting rod until they are tightly fitted against the ventilation duct. Then, begin tightening the first bolts at the corresponding positions. Repeat this process until all corresponding first and second positioning blocks are tightly fitted against the ventilation duct. Furthermore, because the elastic band also fits tightly against the ventilation duct, it not only secures the duct but also prevents it from sliding during installation.

[0020] Finally, after assembling the two lifting lugs with the positioning ring and the third bolt, screw them into the second positioning block and the other upper first positioning block as shown in the figure. Repeat the operation in sequence, as shown in the ventilation duct figure. Multiple sets of devices can be used at the same time. This device can not only be used during installation, but also be installed for long-term hoisting. It has multiple functions.

[0021] Beneficial effects: In this utility model, the ventilation duct construction device can freely change the length and height of the device through two first positioning blocks and two first positioning blocks, as well as the connecting rod in the middle, so as to achieve clamping of ventilation ducts of different specifications.

[0022] In this utility model, the ventilation duct construction device can achieve secondary fixation of the ventilation duct and prevent the ventilation duct from slipping when it is lifted by means of elastic band and hollow shaft. Attached Figure Description
