Description

Technical Field

[0001] This invention belongs to the technical field of equipment for steel structure building construction, and more specifically, this invention relates to a transportation tool for steel structure roofs and its usage method. Background Technology

[0002] During the installation of C-shaped steel roof trusses, panels, and other components in steel structure engineering projects, as well as the later maintenance of steel structure workshops, construction operations frequently involve the transportation of materials and components. Due to factors such as site conditions, small cranes often cannot transport components to the construction site, and large cranes are expensive to operate. Manual handling on the roof truss beams poses significant safety hazards. Therefore, to ensure construction quality, safety, progress, and cost-effectiveness, it is necessary to consider convenient and efficient tools for transporting components. Considering the numerous work points, wide operating areas, and scattered, intermittent nature of steel structure construction and steel structure workshop maintenance, conventional methods typically involve using cranes to transport components that cannot be transported to the construction site due to site limitations. Manual handling increases safety risks, and components transported to the construction site lack 100% safety assurance measures during installation and reinforcement. Using large cranes for site setup is costly, and the safety issues during manual installation are difficult to resolve.

[0003] To address the aforementioned technical problems, various material transport trolleys specifically designed for steel structure roofs have emerged in the prior art, such as... Figure 1 The illustrated transport vehicle for steel structure roofs is capable of efficiently transporting materials on steel structure roofs; however, during use, the following drawbacks were found:

[0004] 1. The frame is welded from several galvanized steel pipes, which makes the assembled transport vehicle have a fixed volume, taking up space during relocation and making it inconvenient to transport.

[0005] 2. When the transport vehicle is moved to the working position, it will make slight movements, which cannot guarantee the stability of the transport vehicle when unloading on the roof;

[0006] 3. Once the transport vehicle is assembled, the position of the traveling mechanism on the transport vehicle remains fixed. However, the spacing of the truss beams in different steel structure buildings will be different, which limits the applicable locations of the transport vehicle. Summary of the Invention

[0069] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0070] Example 1

[0071] This embodiment provides a transportation vehicle for steel structure rooftops, and its specific technical solution is as follows:

[0072] like Figure 2-3 The illustrated steel-structured roof transport vehicle includes;

[0073] The frame 1 is a rectangular basket structure composed of several long steel pipes 101 and several short steel pipes 102 connected together. Specifically, the long steel pipes 101 and short steel pipes 102 are galvanized steel pipes of the same diameter. There are four long steel pipes 101 and several short steel pipes 102. The specific number of short steel pipes 102 is determined according to the length of the long steel pipes 101. The short steel pipes 102 are installed at equal intervals along the length of the long steel pipes 101, for example, the spacing between the short steel pipes 102 is 60cm-120cm. The long steel pipes 101 and short steel pipes 102 are assembled to form... The top of the rectangular basket structure is open; it can be understood that the arrangement of the long steel pipes 101 and the short steel pipes 102 is as follows: the sequential connecting lines of the four long steel pipes 101 in the side view direction form a rectangle, the short steel pipes 102 are arranged at small intervals on the front, back and bottom of the rectangular basket structure, and only one short steel pipe 102 is set at the top and one at the bottom on the left and right sides of the rectangular basket structure. In order to improve the stability of the rectangular basket, short steel pipes 102 are also arranged at the top of the rectangular basket, and the arrangement spacing of the top short steel pipes 102 is 3 to 5 times that of the arrangement spacing of the bottom short steel pipes 102.

[0074] The elastic connecting component 2 is fixed to the long steel pipe 101, and the end of the short steel pipe 102 is temporarily fixed after being inserted into the elastic connecting component 2. Specifically, the elastic connecting components 2 on the two bottom long steel pipes 101 are arranged in pairs. For example, the upper and rear sides of the bottom front long steel pipe 101 are evenly spaced, and the upper and front sides of the bottom rear long steel pipe 101 are evenly spaced. The spacing here is consistent with the arrangement spacing of the short steel pipes 102. Specifically, on the two top long steel pipes 101... The elastic connecting components 2 are arranged such that the position and number of elastic connecting components 2 on the lower sides of the two top long steel pipes 101 are the same as those on the bottom long steel pipe 101, but the number of elastic connecting components 2 on opposite sides of the two top long steel pipes 101 is less than the number of elastic connecting components 2 on the lower sides. In other embodiments, the elastic connecting components 2 on the four long steel pipes 101 are arranged in pairs, and the spacing between adjacent pairs of elastic connecting components 2 on each long steel pipe 101 is the same, and each pair of elastic connecting components 2 is arranged at a right angle. Figure 1 Taking the long steel pipe 101 on the front side of the bottom as an example, the two elastic connecting components 2 in each pair of elastic connecting components 2 are respectively set on the upper side and the rear side of the long steel pipe 101. It can be understood that the elastic connecting components 2 on the other four long steel pipes 101 are set in the same way. The advantage of this setting is that when assembling the frame 1 at the construction site, the four long steel pipes 101 can be used at will, without having to distinguish between the bottom long steel pipe 101 and the bottom long steel pipe 101.

[0075] The walking mechanism 3 is located on the lower side of the frame 1 and is adjustable in lateral position along the frame 1. Since the spacing of the truss beams on the roofs of different steel structure buildings will vary, the walking mechanism 3 is designed to be adjustable in lateral position on the frame 1. This allows the appropriate installation position of the walking mechanism 3 at the bottom of the frame 1 to be selected according to the specific spacing of the truss beams on the steel structure roof at the construction site. After use at the current construction site, the steel structure roof can be transported to the next construction site, and the installation position of the walking mechanism 3 at the bottom of the frame 1 can be selected according to the spacing of the truss beams on the steel structure roof at the next construction site. This makes the steel transport vehicle more adaptable and reusable.

[0076] Anti-derailment structure 4 is installed on the traveling mechanism 3. The anti-derailment structure 4 prevents the traveling mechanism 3 from detaching from the truss beam and can also brake. Specifically, the anti-derailment structure 4 has an overall U-shaped structure. After the anti-derailment structure 4 is installed on the traveling mechanism 3, the anti-derailment structure 4 and the traveling mechanism 3 form a wrapping structure around the truss beam.

[0077] In this embodiment, as Figure 5-7 As shown, the elastic connection component 2 includes:

[0078] The outer sleeve 201 is fixed to the long steel pipe 101; specifically, the outer sleeve 201 is welded to the long steel pipe 101, and the outer diameter of the outer sleeve 201 is the same as the inner diameter of the short steel pipe 102, so as to ensure that the outer sleeve 201 can be inserted into the short steel pipe 102.

[0079] Inner sleeve 202, which is sleeved inside outer sleeve 201, and the inner sleeve 202 can move along the axial direction of outer sleeve 201; when the inner sleeve 202 is in the highest position, the inner sleeve 202 can be locked onto the short steel pipe 102.

[0080] The first spring 203 is located inside the outer sleeve 201. The two ends of the first spring 203 abut against the end of the inner sleeve 202 and the side of the long steel pipe 101, respectively. Thus, under the elastic force of the first spring 203, without applying pressure to the inner sleeve 202, the first spring 203 can drive the inner sleeve 202 to the highest position.

[0081] In this embodiment, as Figure 5-7 As shown, the elastic connection component 2 further includes:

[0082] Inner sleeve 204, the inner sleeve 204 is fixed to the top end of the outer sleeve 201, and the inner sleeve 204 is sleeved on the outer periphery of the inner sleeve 202; specifically, the inner sleeve 204 is integrally formed on the top end of the outer sleeve 201 or fixed to the top end of the outer sleeve 201 by screws;

[0083] An outer ring 205 is fixed to the bottom end of the inner sleeve 202. The outer ring 205 is integrally formed on the bottom end of the inner sleeve 202. The outer ring 205 is located below the inner ring 204 and abuts against the end of the first spring 203. Thus, the inner sleeve 202 is limited by the cooperation of the inner ring 204 and the outer ring 205, preventing the inner sleeve 202 from detaching from the outer sleeve 201 under the elastic force of the first spring 203.

[0084] In this embodiment, as Figure 5-7 As shown, the elastic connection component 2 further includes:

[0085] A limiting protrusion 206 is integrally formed on the outer side wall of the top end of the inner sleeve 202. A sliding hole 1021 communicating with the end of the short steel pipe 102 is provided at the end of the short steel pipe 102. The sliding hole 1021 includes a first vertical hole section 10211, a horizontal hole section 10212, and a second vertical hole section 10213. The first vertical hole section 10211 communicates with the end of the short steel pipe 102. The horizontal hole section 10212 is located at the top end of the first vertical hole section 10211. The second vertical hole section 10213 is located at the end of the horizontal hole section 10212 away from the first vertical hole section 10211. The second vertical hole section 10213 is parallel to the first vertical hole section 10211, and the top end of the second vertical hole section 10213 is an arc-shaped structure that matches the limiting protrusion 206.

[0086] When assembling the short steel pipe 102 and the long steel pipe 101, first insert the limiting protrusion 206 into the opening of the first vertical hole section 10211 of the short steel pipe 102. Then, press the short steel pipe 102 or the long steel pipe 101 so that the limiting protrusion 206 abuts against the horizontal hole section 10212, and the first spring 203 is compressed. When the first spring 203 is contracted to its shortest length, the short steel pipe 102 and the long steel pipe 101 abut against each other. Then, rotate the short steel pipe 102 so that the limiting protrusion 206 slides along the horizontal hole section 10212. When the limiting protrusion 206 reaches the second vertical hole section 10213, the first spring 203 loses the constraint of the horizontal hole section 10212 and pushes the inner sleeve 202 to drive the limiting protrusion 206. 6 moves toward the end of the second vertical hole section 10213, and finally the limiting protrusion 206 will be engaged with the end of the second vertical hole section 10213. Without applying external force to push the limiting protrusion 206, the limiting protrusion 206 will be stably engaged with the end of the second vertical hole section 10213 under the elastic force of the first spring 203, thereby stably connecting the long steel pipe 101 and the short steel pipe 102. It should be noted that the limiting protrusions 206 of the inner sleeves 202 on the two opposite long steel pipes 101 are oriented in the same direction, while the sliding holes 1021 at both ends of the short steel pipe 102 are mirror symmetrical, so that both ends of the short steel pipe 102 can be connected to the two opposite long steel pipes 101 at the same time.

[0087] like Figure 4 As shown, the walking mechanism 3 includes:

[0088] Two support beams 301 are installed on the lower side of the frame 1; the support beams 301 are angle steel, and the length of the support beams 301 is greater than the front and rear width of the frame 1.

[0089] Two track wheels 302 are rotatably mounted between the ends of two support beams 301, that is, the two track wheels 302 are located on the front and rear ends of the support beams 301 extending out of the frame 1.

[0090] like Figure 4 As shown, the walking mechanism 3 also includes:

[0091] Channel steel 303 is fixed to the upper side of the end of the support beam 301, that is, channel steel 303 is fixed to the front and rear ends of the support beam 301 extending out of the frame 1; specifically, channel steel 303 is fixedly connected to the support beam 301 by bolts.

[0092] A locking component 304 is installed on the channel steel 303, and the locking component 304 can temporarily fix the channel steel 303 to the corresponding long steel pipe 101.

[0093] like Figure 8As shown, the locking assembly 304 includes:

[0094] Guide rod 3041, the guide rod 3041 is fixed on the inner side wall of the channel steel 303;

[0095] The insertion rod 3042 has a stepped hole 3043, and the guide rod 3041 passes through the stepped hole 3043, thereby enabling the insertion rod 3042 to slide back and forth along the length direction of the guide rod 3041; the side wall of the long steel pipe 101 has equally spaced insertion holes 1011, and the spacing between two adjacent insertion holes 1011 is sufficient to ensure that the insertion rod 3042 on the channel steel 303 is inserted into the corresponding insertion hole 1011;

[0096] The second spring 3044 is sleeved on the guide rod 3041. One end of the second spring 3044 abuts against the bottom wall of the large diameter section of the stepped hole 3043, and the other end abuts against the side wall of the channel steel 303. Under the elastic force of the second spring 3044, the insertion rod 3042 can be inserted into the long steel pipe 101 to fix the channel steel 303 on the long steel pipe 101.

[0097] An inverted U-shaped locking rod 3045 is fixed to the end of the insert rod 3042 and can be engaged with the end of the channel steel 303 away from the long steel pipe 101.

[0098] In this embodiment, as Figure 4 and Figure 8 As shown, the vertical plate at the end of the channel steel 303 away from the long steel pipe 101 is provided with a notch and an arc-shaped hole 3031 communicating with the notch. When it is necessary to remove the walking mechanism 3, by pulling the inverted U-shaped locking rod 3045, the insertion rod 3042 is moved towards the end of the channel steel 303, so that the insertion rod 3042 gradually disengages from the insertion hole 1011. When the inverted U-shaped locking rod 3045 passes through the notch, the insertion rod 3042 completely disengages from the insertion hole 1011. Then, the inverted U-shaped locking rod 3045 is rotated to slide along the arc-shaped hole 3031. During the rotation of the inverted U-shaped locking rod 3045, the opening of the inverted U-shaped locking rod 3045 will be stuck on the side wall of the arc-shaped hole 3031. That is, at this time, the second spring 3044 cannot push the insertion rod 3042 into the insertion hole 1011, and finally the channel steel 303 is removed from the long steel pipe 101.

[0099] like Figure 2 , Figure 4 As shown, the anti-derailment structure 4 includes:

[0100] Two symmetrically arranged inverted L-shaped plates 401 are installed at the ends of the support beam 301. Specifically, the inverted L-shaped plates 401 are bolted to the ends of the support beam 301 extending from the front and rear sides of the frame 1. The channel steel 303 and the inverted L-shaped plates 401 are installed on the ends of the support beam 301 by the same bolt.

[0101] The lifting plate 402 has a strip hole for the inverted L-shaped plate 401 to pass through. The strip hole ensures the smooth lifting of the lifting plate 402 and ensures that friction is generated when the lifting plate 402 rises to the lower side of the truss beam, so as to play a braking role.

[0102] An adjusting screw 403 is rotatably mounted on the support beam 301, and its end is threadedly connected to the lifting plate 402. Specifically, two adjusting screws 403 are installed on the support beam 301, so the lifting plate 402 is threadedly connected to both adjusting screws 403 simultaneously. When both adjusting screws 403 are rotated simultaneously, the lifting plate 402 can be driven to rise and fall. When there is a certain gap between the lifting plate 402 and the lower side of the truss beam, it will not hinder the normal movement of the traveling mechanism 3. However, the lifting plate and the two inverted L-shaped plates 401 form a U-shaped structure, which, after cooperating with the channel steel 303, wraps around the truss beam to prevent the traveling mechanism 3 from derailing. When the lifting plate 402 rises to the point of contacting the lower side of the truss beam, the friction between the lifting plate 402 and the lower side of the truss beam acts as a brake.

[0103] like Figure 4 As shown, the anti-derailment structure 4 further includes:

[0104] Friction pad 404 is disposed on the upper side of the lifting plate 402. The friction pad 404 is made of rubber, thereby enhancing the friction between the lifting plate 402 and the lower side of the truss beam, and maintaining effective braking when braking.

[0105] like Figure 8As shown, the channel steel 303, the support beam 301, and the inverted L-shaped plate 401 are all provided with slots 6 at their ends. The adjusting screw 403 is provided with an annular groove (it can be understood that the inner diameter of the annular groove is smaller than the diameter of the adjusting screw 403). The inner diameter of the annular groove is consistent with the width of the slot 6, thus forming a form in which the adjusting screw 403 is engaged at the slot 6, that is, the adjusting screw 403 cannot move up and down, but can only rotate. Due to the presence of slots 6 at the ends of the channel steel 303, the support beam 301, and the inverted L-shaped plate... Both ends of 401 are provided with slots 6, so that after the two adjusting screws 403 are inserted into the slots 6, and the lifting plate 402 is threaded onto the adjusting screws 403, neither adjusting screw 403 can move left or right. With the combination of the slots 6 and the annular groove, the lifting plate 402 is stably installed on the inverted L-shaped plate 401 to effectively prevent derailment and brake. In order to allow the adjusting screws 403 to rotate smoothly, a handle 4031 is provided on the top of the adjusting screws 403.

[0106] like Figure 8-10 As shown, the transport vehicle for the steel structure roof also includes:

[0107] Anti-rollover component 5;

[0108] The anti-runaway component 5 includes:

[0109] Ratchet 501 is disposed at the end of the track wheel 302, and the outer diameter of ratchet 501 is larger than the outer diameter of track wheel 302, thereby preventing the track wheel 302 from deviating and derailing when there is no anti-derailment structure 4 to effectively prevent derailment.

[0110] A pawl 502 is rotatably mounted on a channel steel 303 on the upper side of the support beam 301. Specifically, a mounting plate 3032 is provided on the channel steel 303, and the pawl 502 is rotatably mounted on the mounting plate 3032 via a rotating shaft. The end of the pawl 502 can be engaged with a ratchet 501. A through hole 3033 is provided on the channel steel 303 for the pawl 502 to pass through.

[0111] A spring plate 503 is located above the pawl 502. The spring plate 503 pushes the pawl 502 to engage with the ratchet 501. Specifically, the end of the spring plate 503 is fixed to the mounting plate 3032. The spring plate 503 is always in contact with the pawl 502 to ensure that the pawl 502 can engage with the ratchet 501.

[0112] In specific implementation, a ratchet 501 is only installed on the track wheel 302 on the front side of the frame 1, and a mounting plate 3032 is installed on the channel steel 303 on the front side of the frame 1. Then, a pawl 502 and a spring plate 503 are installed on the mounting plate 3032. The slot on the ratchet 501 for the pawl 502 to engage faces the rear of the frame 1. In this way, when the transport vehicle is hoisted onto the steel structure roof, the ratchet 501 and track wheel 302 are kept facing the direction of travel of the frame 1. For sloping roofs, the transport vehicle needs to be hoisted to the lower eaves of the steel structure roof to prevent the transport vehicle from slipping when moving from the lower to the higher position along the sloping roof. For flat roofs, the transport vehicle can be hoisted to any eaves of the steel structure roof.

[0113] The assembly process of the steel structure roof transport vehicle provided in this embodiment is as follows:

[0114] The assembly of the frame 1 involves transporting the components of the transport vehicle to the construction site, dividing the four long steel pipes 101 into two groups to serve as the front and rear sides of the frame 1, and then installing the corresponding short steel pipes 102 of the two groups of long steel pipes 101 through the elastic connection component 2. Then, the short steel pipes 102 at the bottom of the two groups of long steel pipes 101 are installed, and a small number of short steel pipes 102 are installed on the top long steel pipes 101.

[0115] The assembly of the walking mechanism 3 involves dividing the four support beams 301 into two groups. Each support beam 301 has a channel steel 303, an inverted L-shaped plate 401, and a track wheel 302 installed at both ends. When installing the channel steel 303 and the track wheel 302, care should be taken to ensure that the track wheel 302 with the pawl 502 and the track wheel 302 with the ratchet 501 in the two groups of support beams 301 are on the same side.

[0116] The installation of the walking mechanism 3 involves securing the insertion rod 3042 on the channel steel 303 to the side wall of the arc-shaped hole 3031 via the inverted U-shaped locking rod 3045. The two walking mechanisms 3 are then arranged in suitable positions according to the spacing of the truss beams at the construction site (ensuring that the walking mechanism 3, after the transport vehicle is hoisted onto the steel structure roof, abuts against any two truss beams). The assembled vehicle frame is then placed on the walking mechanism 3 (ensuring that the insertion hole 1011 of the long steel pipe 101 corresponds to the insertion rod 3042). After rotating the inverted U-shaped locking rod 3045 to a vertical position, the insertion rod 3042 is inserted into the insertion hole 1011 under the elastic force of the second spring 3044.

[0117] The installation of the anti-derailment structure 4 is completed after the transport vehicle is hoisted onto the steel structure roof. Since the installation of the inverted L-shaped plate 401 was completed when assembling the walking mechanism 3, after the transport vehicle is hoisted onto the steel structure roof, the lifting plate 402 can be installed by adjusting the screw 403. When installing the lifting plate 402, pay attention to leaving a gap between the lifting plate 402 (i.e., the friction pad 404 on the upper side of the lifting plate 402) and the truss beam.

[0118] The transportation tool provided by the present invention is used to transport roof panels and necessary reinforcement components for steel structure roofs. In order to facilitate the pushing and standing of construction workers, a support plate can be installed between two adjacent short steel pipes 102 at the bottom of the frame 1 so that construction workers can stand during construction. When the roof panels are loaded into the frame, space must be left for construction workers to stand and push the transportation tool.

[0119] Example 2

[0120] A method of using a transportation vehicle for a steel structure roof, comprising the transportation vehicle for a steel structure roof as described in Example 1, wherein the method of use includes:

[0121] Step S1: Determine the position of the assembled traveling mechanism according to the arrangement spacing of the steel structure roof truss beams and install the frame 1 and the traveling mechanism 3.

[0122] This step includes the assembly and installation of the running gear 3 of the frame 1;

[0123] The process of assembling the frame 1 involves transporting the components of the transport vehicle to the construction site, dividing the four long steel pipes 101 into two groups to serve as the front and rear sides of the frame 1, and then installing the corresponding short steel pipes 102 of the two groups of long steel pipes 101 through the elastic connection component 2. Then, the short steel pipes 102 at the bottom of the two groups of long steel pipes 101 are installed, and a small number of short steel pipes 102 are installed on the top long steel pipes 101.

[0124] In the assembly process of the walking mechanism 3, the four support beams 301 are divided into two groups. Each support beam 301 is equipped with a channel steel 303, an inverted L-shaped plate 401 and a track wheel 302 at both ends. When installing the channel steel 303 and the track wheel 302, care should be taken to ensure that the track wheel 302 with the pawl 502 and the track wheel 302 with the ratchet 501 in the two groups of support beams 301 are on the same side.

[0125] During the installation of the walking mechanism 3, the insertion rod 3042 on the channel steel 303 is locked in place on the side wall of the arc hole 3031 by the inverted U-shaped locking rod 3045. The two walking mechanisms 3 are arranged in a suitable position according to the spacing of the truss beams at the construction site (so that the walking mechanism 3 after the transport vehicle is hoisted to the steel structure roof can abut against any two truss beams). Then, the assembled frame is placed on the walking mechanism 3 (when placing it, ensure that the insertion hole 1011 of the long steel pipe 101 corresponds to the insertion rod 3042). Then, after rotating the inverted U-shaped locking rod 3045 to the vertical position, the insertion rod 3042 is inserted into the insertion hole 1011 under the elastic force of the second spring 3044.

[0126] Step S2: Use a transport vehicle to hoist the steel structure roof, which has been positioned with the walking mechanism 3 adjusted, onto the steel structure roof, so that the walking mechanism 3 presses down on the truss beam;

[0127] The truss beams used to support the two traveling mechanisms 3 are not adjacent. Since the assembled frame 1 can be up to 25 meters long, and the spacing between the truss beams does not exceed 1.8 meters, in order to maintain the balance of the support points of the traveling mechanism 3 on the frame 1, there will be multiple truss beams between the truss beams used to support the traveling mechanism 3.

[0128] When hoisting the transport vehicle onto the steel structure roof, keep the end of the traveling mechanism 3 with the anti-slip component 5 facing forward in the direction of travel of the transport vehicle;

[0129] If the steel structure roof is a sloping roof, the transport vehicle needs to be hoisted to the lower eaves of the steel structure roof;

[0130] Before hoisting the transport vehicle onto the steel structure roof, the necessary roof panels and reinforcements can be installed inside the vehicle frame. Alternatively, the transport vehicle can be hoisted onto the steel structure roof first, and then the roof panels and reinforcements can be hoisted into the transport vehicle.

[0131] Step S3: Install the anti-derailment structure, ensuring that the anti-derailment structure and the traveling mechanism wrap around the truss beam;

[0132] The installation of the anti-derailment structure 4 is completed after the transport vehicle is hoisted to the steel structure roof. Since the installation of the inverted L-shaped plate 401 was completed when assembling the walking mechanism 3, after the transport vehicle is hoisted to the steel structure roof, the lifting plate 402 can be installed by adjusting the screw 403. When installing the lifting plate 402, pay attention to leaving a gap between the lifting plate 402 (i.e., the friction pad 404 on the upper side of the lifting plate 402) and the truss beam.

[0133] Step S4: Push the steel roof transport vehicle along the truss beam. Once it reaches the designated position, brake it using the anti-derailment structure.

[0134] During this process, if the steel structure roof is a sloping roof, the transport vehicle will not slide backward during the process of moving from a low position to a high position under the action of the anti-slip component 5.

[0135] When the transport vehicle moves to the unloading position, the lifting plate 402 is driven to move upward by rotating the adjusting screw 403 until the friction pad 404 presses against the lower side of the truss beam to brake, and then the roof panels and the required reinforcements can be unloaded.

[0136] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
