Abstract
Description
Technical Field
[0001] This utility model relates to the field of counterweight transportation technology, and in particular to a vehicle for transporting counterweights. Background Technology
[0002] In the construction of distributed photovoltaic power stations, counterweights, as the basic fixing units for photovoltaic modules, need to be deployed in large numbers on rooftops and other construction sites. Traditionally, counterweights are typically precast concrete structures with embedded connecting rods, resulting in large individual weights and heavy reliance on manual handling during transportation. However, this type of operation has the following drawbacks:
[0003] 1. Manual handling requires multiple people to work together, and the limited roof space makes the movement path complicated, making it difficult to meet the needs of large-scale construction in terms of handling efficiency;
[0004] 2. High-intensity repetitive work can easily lead to worker fatigue, and the rooftop environment also poses a risk of slipping and falling, so the safety of the work urgently needs to be improved;
[0005] 3. Due to the lack of adaptable lifting structures, existing transport vehicles cannot directly connect to construction sites. They need to go through multiple stages of transfer, including "manual loading - vehicle short-distance transfer - manual unloading", which leads to a significant increase in time and labor costs. Utility Model Content
[0006] In view of the shortcomings of the existing technology, this utility model provides a counterweight transport vehicle to solve the technical problems of low transportation efficiency and high labor intensity of traditional transport vehicles in related technologies.
[0007] This utility model provides a counterweight transport vehicle for use in distributed photovoltaic power stations. The counterweight is equipped with a pre-embedded rod, and the transport vehicle includes:
[0008] The main frame includes a support, a support leg assembly, and a pulley assembly connected in sequence. The support leg assembly and the pulley assembly each have multiple support legs and multiple pulleys, and the multiple support legs and multiple pulleys are arranged in a one-to-one correspondence.
[0009] A hoisting device is provided on the support. The hoisting device has fixed points for fixing the embedded rod and hoisting the counterweight.
[0010] An anti-sway assembly includes a bracket and at least one set of limiting rods. The bracket is disposed on the support leg, and the limiting rods are threaded through the bracket to abut or release the counterweight during the hoisting process.
[0011] Furthermore, the multiple support legs are arranged at equal intervals.
[0012] Furthermore, the upper end of the support leg is inclined downward from its lower end.
[0013] Furthermore, the bracket includes a plurality of support rods, the number of which is equal to the number of the plurality of support legs, and each support rod is used to connect two adjacent support legs.
[0014] Furthermore, the limiting rods are arranged in pairs and are positioned opposite each other at different support rods.
[0015] Furthermore, push blocks are provided at both proximal ends of the limiting rods in the same group; and / or
[0016] The limiting rod in the same group is provided with rotating blocks at both ends.
[0017] Furthermore, the embedded rod has a threaded structure, and the fixing point includes multiple through holes and multiple locking nuts that are arranged in a one-to-one correspondence. The embedded rod can be selectively inserted into any of the through holes and fixed by the locking nuts.
[0018] Furthermore, a plurality of first reinforcing rods are provided between the support and the bracket, and the first reinforcing rods are used to connect two adjacent support legs.
[0019] Furthermore, a plurality of second reinforcing rods are provided between the support and the first reinforcing rod.
[0020] Compared to existing technologies, this utility model has the following advantages: the sequentially connected supports, support legs, and pulley system constitute the main frame of the transport vehicle, and the distributed load-bearing structure disperses the load pressure, preventing concentrated pressure on the roof structure; at the same time, it makes the main frame structure more compact, making it suitable for different construction environments. Furthermore, the fixed points of the hoisting equipment can be locked using the existing embedded rods of the counterweight blocks, eliminating the need for manual binding and shortening the single transport time; in addition, the main frame and hoisting equipment work together to achieve flexible translation and precise placement of the counterweight blocks, reducing the time spent on repeated handling and adjustment, thereby improving the transport efficiency of the counterweight blocks and reducing labor intensity; and the threaded limit rods can adjust the lateral resistance force on the counterweight blocks, suppressing their swaying and offset during hoisting and preventing collision damage to the counterweight blocks caused by shaking.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0028] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.
[0029] In the embodiments of this utility model, such as Figures 1-3 As shown, the transport vehicle for the counterweight includes: a main frame, a hoisting device 4, and an anti-sway component 5; the main frame includes a support 1, a support leg assembly, and a pulley assembly connected in sequence, wherein the support leg assembly and the pulley assembly each have multiple support legs 2 and multiple pulleys 3, and the multiple support legs 2 and multiple pulleys 3 are arranged in a one-to-one correspondence; the hoisting device 4 is located on the support 1, and the hoisting device 4 has fixed points for fixing the embedded rod and hoisting the counterweight; the anti-sway component 5 includes a bracket and at least one set of limiting rods 502, the bracket is located on the support leg 2, and the limiting rods 502 are threaded through the bracket to abut or release the counterweight during the hoisting process.
[0030] Specifically, in this embodiment of the utility model, the counterweight is provided with a pre-embedded rod, that is, one end of the pre-embedded rod is pre-embedded when the concrete counterweight is poured, and the other end extends out of the counterweight for connection with the photovoltaic bracket so as to install the counterweight in the corresponding position.
[0031] In this embodiment of the invention, a support 1, a support leg assembly, and a pulley assembly are arranged sequentially along the vertical direction, and each of the support leg assembly and the pulley assembly includes multiple support legs 2 and multiple pulleys 3 (e.g., ...). Figure 1 As shown in the example (using four support legs 2 and four pulleys 3), the upper end of the support leg 2 is fixed to the support 1, and its lower end is connected to the pulley 3, thus constructing the main frame structure, which can slide using the pulley 3. In addition, the four support legs 2 extend in different directions to distribute the load pressure, avoid concentrated pressure on the roof structure, and make the main frame more compact to adapt to complex terrains such as roofs.
[0032] In this embodiment of the invention, a lifting device 4 is provided at the support 1. The lifting device 4 includes a drive unit and a lifting unit. The drive unit includes a drive gear, a chain, and a hook. The drive gear is located at the support 1, and the chain is connected to the hook. The chain meshes with the drive gear to move the hook closer to or away from the support 1. Alternatively, the drive unit can be an electric / manual hoist or other lifting device. The lifting unit includes a connected lifting ring and a lifting plate 401. The hook can be hung at the lifting ring, and the lifting plate 401 has a fixed point for fixing the embedded part of the counterweight at that fixed point. With the cooperation of the drive unit, the counterweight can be lifted and suspended above the ground. In this way, on the one hand, the binding process before transportation can be eliminated, and the existing embedded parts of the counterweight blocks can be used for connection, which greatly shortens the single hoisting cycle; on the other hand, the manual handling and loading and unloading process can also be eliminated, further improving transportation efficiency; at the same time, the counterweight blocks can be quickly transported to the designated location in cooperation with the main frame.
[0033] In this embodiment of the invention, since it is only necessary to lift the counterweight to a position suspended above the ground, the lifting height does not need to be too large. Therefore, to prevent the counterweight from swinging significantly during the lifting and traction process, a bracket is provided at the support leg 2, and a limiting rod 502 can be threaded through the bracket (i.e., the limiting rod 502 can be a limiting screw). By reversing the limiting rod 502, the distance between one end of the limiting rod 502 and the bracket can be changed, so as to abut or release the counterweight between them, avoiding collisions caused by the counterweight swaying. In addition, to further limit the counterweight to the lifting position, at least one set of limiting rods 502 is provided. A set of limiting rods 502 cooperates to clamp the counterweight between them. Of course, since the bracket is provided at the support leg 2, it can improve the overall structural strength of the main frame and / or improve the structural strength of the corresponding support leg 2.
[0034] This embodiment, through the cooperation of the main frame and lifting equipment, enables the transport vehicle to perform both lifting and short-haul transportation functions. It can directly lift the counterweight from the ground and transport it to the target location, eliminating the inefficient process of traditional multi-stage "manual + vehicle" transfer. Furthermore, the threaded limit rod 502 adjusts the lateral resistance force on the counterweight in real time, suppressing swaying and offset during lifting and preventing collision damage or misalignment of the counterweight due to shaking. Simultaneously, operators do not need to support the counterweight at close range, reducing the risk of falling objects from height and improving the controllability of the operation.
[0035] like Figure 1 As shown, in one embodiment, the plurality of support legs 2 are arranged at equal intervals; this can further distribute the load pressure.
[0036] like Figure 1As shown, in one embodiment, the upper end of the support leg 2 is inclined downward from its lower end; so that a near-triangular stable structure is formed between two adjacent support legs 2, thereby improving the structural strength of the main frame.
[0037] like Figure 1 , Figure 2 As shown, in one embodiment, the bracket includes multiple support rods 501, the number of which is equal to the number of support legs 2, and each support rod 501 is used to connect two adjacent support legs 2. Specifically, in order to install the bracket at each support leg 2, this embodiment defines the bracket as including multiple support rods 501 (since there are four support legs 2 in this embodiment, the number of support rods 501 is also four), so that two adjacent support legs 2 are connected by a support rod 501, thereby improving the structural strength between two adjacent support legs 2 and avoiding the risk of bending or breaking of the support leg 2. Of course, in order to further improve the structural strength of the main frame, the four support rods 501 can be connected end to end to form a frame structure and fixed at each support leg 2. In this way, it can not only be used as a reinforcing rib of the main frame, but also facilitate the installation of the limiting rod 502 at the corresponding position to clamp the counterweight between them.
[0038] like Figure 1 , Figure 2 As shown, in one embodiment, the limiting rods 502 are arranged in pairs and are positioned opposite each other at different support rods 501. Specifically, to prevent the counterweight from swaying significantly, in this embodiment, the two limiting rods 502 arranged opposite each other are grouped together, and the two limiting rods 502 in the same group are threaded through different support rods 501 to facilitate clamping the opposite end faces of the counterweight. Figure 2 As shown, in this embodiment, a limiting rod 502 is provided at each support rod 501, so the anti-sway component 5 in this embodiment has two sets of limiting rods 502.
[0039] like Figure 2 As shown, in one embodiment, push blocks 503 are provided at both proximal ends of the limiting rods 502 in the same group; the push blocks 503 can increase the contact area between the limiting rods 502 and the counterweight, so as to clamp the counterweight between them. Of course, in other embodiments, rotating blocks (not shown) are provided at both distal ends of the limiting rods 502 in the same group. The rotating blocks can serve as the rotation force application points of the limiting rods 502, so as to rotate the limiting rods 502 in both directions, so as to make them abut against or release the counterweight.
[0040] like Figure 3As shown, in one embodiment, the embedded rod has a threaded structure, and the fixing point includes a plurality of through holes 402 and a plurality of locking nuts arranged in a one-to-one correspondence. The embedded rod can be selectively inserted through any of the through holes 402 and fixed by the locking nuts. Specifically, in order to fix the counterweight at the lifting plate 401 so as to carry out lifting operations under the traction of the drive unit, this embodiment sets a fixing point at the lifting plate 401, and the fixing point includes a through hole 402 and a locking nut. Thus, when the embedded rod is an embedded screw rod, because its surface has a threaded structure, the embedded rod can be passed through the through hole 402 and locked by the locking nut, thereby fixing the counterweight at the lifting plate 401. Furthermore, multiple through holes 402 and locking nuts can be provided. On the one hand, this can accommodate multiple embedded rods of the same counterweight, increasing the connection points between the lifting plate 401 and the counterweight to improve the stability of the counterweight. On the other hand, the corresponding through hole 402 can be reasonably selected according to the embedded position of the embedded rod to improve the versatility of this transport vehicle.
[0041] like Figure 1 , Figure 4 As shown, in one embodiment, a plurality of first reinforcing rods 6 are provided between the support 1 and the bracket, and the first reinforcing rods 6 are used to connect two adjacent support legs 2. Specifically, in order to further improve the structural strength of the main frame, this embodiment provides first reinforcing rods 6 between two adjacent support legs 2, so that the two ends of the first reinforcing rods 6 are respectively fixed at the corresponding support legs 2, thereby improving the structural strength of the support legs 2 at that point. At the same time, the first reinforcing rods 6 are located between the support 1 and the bracket, which can avoid stress concentration and prevent deformation of the support legs 2.
[0042] Furthermore, such as Figure 4 As shown, a plurality of second reinforcing rods 7 are provided between the support 1 and the first reinforcing rod 6. The number of second reinforcing rods 7 is the same as the number of support legs 2, and they are arranged parallel to the corresponding support legs 2, so as to replace the single support leg 2 with a partially double-layer support leg 2 structure, thereby further improving the structural strength of the support leg 2.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
