Description

Technical Field

[0001] This utility model belongs to the field of building installation equipment technology, and specifically relates to a roof color steel plate pulley traction auxiliary device. Background Technology

[0002] During the installation of corrugated steel panels in circular coal bunkers, traditional hauling methods easily lead to collisions between the panels and roof purlins or other building materials, causing deformation or damage. Furthermore, during vertical transport, the panels may vibrate due to wind or insecure fixing, causing them to detach from their fixed positions, posing a serious safety hazard. To improve installation efficiency and safety, reduce the labor intensity of operators, and ensure reliable operation, a pulley traction auxiliary device for roof corrugated steel panels is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects and propose a pulley traction auxiliary device for roof color steel plates. It aims to solve the problems of color steel plates being prone to bumping, shaking and falling off during the towing process, improve installation efficiency and safety, and reduce the labor intensity of operators.

[0004] The specific technical solution is as follows:

[0012] Furthermore, the above scheme includes several reinforcing ribs on the side of the frame away from the side opening.

[0013] Furthermore, the fixing device includes a fixing member and a flange with a through hole. The flange is symmetrically arranged on both sides of the opening on the side of the frame.

[0027] The embodiments of the utility model are further described in detail below with reference to the accompanying drawings, so that the purpose, technical solution and technical effect of the utility model can be more clearly presented.

[0028] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figure 1-2 As shown, this utility model provides a pulley traction auxiliary device for roof color steel plate 4, including a frame 1, universal pulleys 3, fixing device 5, and traction rope. The frame 1 adopts a rectangular structure design, with a side opening 2 to accommodate the end of the color steel plate 4. Three sets of universal pulleys are symmetrically distributed on the upper and lower surfaces of the opening. The fixing device 5 secures the color steel plate 4 in an adjustable manner. The traction rope connects the frame 1 to an external traction power source to form a closed-loop traction system.

[0030] In practice, the traction mechanism is located at the top of the circular coal bunker. At ground level, operators insert the end of the color steel plate 4 into the side opening 2 of the frame 1. After the plate is positioned and fixed using the fixing device 5, the traction mechanism applies tension via a traction rope. Upon lifting, the universal pulley 3 first forms rolling contact with the purlins of the circular coal bunker roof, effectively reducing the coefficient of sliding friction. Specifically, the universal pulley 3 group at the side opening 2 of the frame 1 forms a double-pivot rolling structure, which can adaptively adjust the angle between the color steel plate 4 and the contact surface, avoiding localized stress concentration in the plate caused by traditional dragging.

[0031] Here, frame 1 is constructed from galvanized square tubing welded together, and the universal pulleys 3 are welded to frame 1. To enhance the deformation resistance and corrosion resistance of frame 1, this embodiment uses galvanized square tubing with a wall thickness of 2.5mm, and forms continuous welds using carbon dioxide shielded welding. This increases the overall rigidity of frame 1 by more than 35%, and the welded universal pulley 3 mounting base can withstand a radial load of 200kg without displacement.

[0032] Here, two sets of omnidirectional pulleys 3 are provided. One set is located at the corner of one end face near the side opening 2, and the other set is located at the corner of the other end face away from the side opening 2. Each set of omnidirectional pulleys 3 includes two pulleys. To solve the problem of deflection torque easily generated by a single pulley set, this embodiment arranges a double pulley set at the diagonal position of the frame 1. This creates a four-point support structure during traction, which, according to actual measurements, can reduce the lateral sway of the plate by 60%.

[0033] In this embodiment, several reinforcing ribs are provided on the side of frame 1 away from the side opening 2. To prevent bending deformation of frame 1 during long-distance traction, 2-3 transverse reinforcing ribs are welded to the back of frame 1. This significantly improves the bending section modulus of frame 1.

[0034] like Figure 3 As shown, the fixing device 5 includes a fixing member and a flange 7 with a through hole. The flange 7 is symmetrically arranged on both sides of the side opening 2 of the frame 1, specifically located in the middle of the side opening 2. The fixing member can pass through the corresponding fixing hole at the end of the color steel plate 4 and the through hole of the flange 7 to fix the color steel plate 4. First, during hoisting, the end of the color steel plate 4 is inserted into the side opening 2 of the frame 1. The color steel plate 4 can be multiple plates stacked. After stacking, holes are pre-drilled at the end of the color steel plate 4, and these holes are aligned with the through holes of the flange 7. This allows the fixing member to pass through the through hole of the flange 7 and the pre-drilled hole at the end of the color steel plate 4 in sequence, thereby fixing the frame 1 and the color steel plate 4. It should be clear that if the color steel plate 4 is fixed by compression, there is a risk that the color steel plate 4 will slip. Therefore, holes are pre-drilled at the end of the color steel plate 4 to ensure that the frame 1 and the color steel plate 4 can be fixed together by the fixing member.

[0035] Here, the fastener can be a fixing rope, which passes through the corresponding fixing holes at the ends of the color steel plate 4 and the through holes of the flange 7 to bind the color steel plate 4 to the frame 1.

[0036] Of course, the fastener can also be a pin structure, such as... Figure 4 As shown, the pin slides through the through hole of the flange 7 and the through hole at the end of the color steel plate 4 to fix the color steel plate 4. The pin can be an anti-detachment pin, so that it can quickly pass through the through hole of the flange 7 and the pre-drilled hole at the end of the color steel plate 4 to form a connection.

[0037] like Figure 3 and 4 As shown, a lifting lug 6 is provided at one end of the frame 1 away from the side opening 2 of the frame 1. The lifting lug 6 has a lifting hole for connecting the traction rope.

[0038] When in use, the traction rope can be tied to the lifting lug 6; or it can act as a fixed rope at the movable end while connecting the frame 1; that is, after connecting to the frame 1, a longer movable end is left for fixing the color steel plate 4 and the frame 1.

[0039] The technical advantages of this invention are as follows: the combined structure of frame 1 and universal pulley 3 transforms sliding friction into rolling friction, with actual measurements showing a 72% reduction in traction resistance; the dual-mode fixing device 5 improves the reliability of plate fixing to 99.8%; and the reinforcing rib structure extends the device's service life by more than three times. Engineering application verification shows that this device can increase daily installation volume by 40%, and reduce the plate damage rate from 8.3% in traditional processes to below 0.5%.

All equivalent changes, equivalent substitutions or modifications made within the technical spirit and principles indicated by the present utility model should be included within the scope of patent protection covered by the present utility model.
