Abstract
Description
Technical Field
[0001] This invention relates to the technical field of building construction, and more specifically, to a block handling trolley and its method of use. Background Technology
[0002] Currently, in masonry construction, the handling and stacking of blocks usually requires the use of handcarts. Workers use these handcarts to transport the blocks to the construction site. However, existing handcarts pose two major safety hazards during use: First, traditional block trolleys are often poorly designed and not properly sized for the blocks, resulting in improper placement of blocks, especially overloading. This can easily lead to blocks falling during transport, causing material damage and reducing construction efficiency; it also poses a risk of injury from falling blocks. Furthermore, due to the limited length of the bottom rails on existing block trolleys, workers often place fewer blocks in the first compartment and more behind it, resulting in a top-heavy situation with too few blocks at the bottom and too many at the top, creating a significant safety hazard.
[0003] Second: In bricklaying construction, there is often a rush to meet deadlines. In such cases, workers often lack safety awareness and tend to be impatient or even reckless in their work. When stacking blocks, they often pull away the block carts before the blocks are properly placed. Furthermore, because there is not enough safety protection around the block stacks, there is a great safety risk.
[0004] Based on the aforementioned technical issues, there is an urgent need for a solution that can significantly improve the safety of block trolley construction. Summary of the Invention
[0005] In view of the above problems, the purpose of this invention is to provide a block handling trolley and its method of use, so as to solve the problem that the existing block trolley construction scheme has great safety risks.
[0006] The present invention provides a block transport trolley, including a trolley flatbed, on both sides of which are fixed support sleeves arranged along the vehicle body direction; wherein, a transmission rod passes through the support sleeve, and a rotating stop is provided at the front end of the trolley flatbed, one end of the transmission rod being connected to the rotating stop; and, by rotating the transmission rod, the rotating stop is driven to open or close, so that the rotating stop limits and releases the blocks to be transported on the trolley flatbed.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] The structure of the block handling trolley provided by this invention is described in detail below. Figure 1 The three-dimensional structure of a block transport trolley provided according to an embodiment of the present invention is shown. Figure 2 The front view of the block handling trolley provided according to an embodiment of the present invention is shown. Figure 3 The side view of a block handling trolley provided according to an embodiment of the present invention is shown. Figure 4 The diagram shows a top view of a block handling trolley provided according to an embodiment of the present invention.
[0023] Combination Figures 1 to 4 As shown in the figure, the block handling trolley provided in this embodiment of the invention includes a trolley flatbed 3 as the main bearing platform of the trolley. Support sleeves 6 are fixed on both the inner and outer sides of the trolley flatbed 3 and are arranged along the vehicle body direction. The length of the support sleeve 6 is greater than the length of the trolley flatbed 3. The front end of the support sleeve 6 needs to correspond to (e.g., be aligned) with the front end of the trolley flatbed 3. The rear end of the support sleeve 6 extends to the rear of the trolley flatbed 3, which makes it convenient for industrial personnel to push the entire block handling trolley by hand.
[0024] Specifically, to prevent workers from loading too many blocks, a rotating support is provided at the front end of the trolley flatbed 3, and a transmission rod passes through the support sleeve 6. The front end of the transmission rod corresponds to the front end of the support sleeve 6, and the rear end of the transmission rod corresponds to the rear end of the support sleeve 6 (e.g., aligned). Furthermore, the front end of the transmission rod is connected to the rotating support, and a rotating handle 12 located outside the support sleeve 6 is fixedly connected to the rear end of the transmission rod.
[0025] In actual use, to facilitate loading blocks, the operator will rotate the rotating handle 12 (preferably 90 degrees) to move the two rotating supports to the outside of the trolley plate 3 (the two rotating supports are located on both sides of the trolley plate 3). At this time, the two rotating supports are in the open state. Then the operator can load blocks onto the trolley plate 3. After the blocks are loaded, the operator will rotate the rotating handle 12 to move the two rotating supports to the inside of the trolley plate 3 (both rotating supports are located at the front of the trolley plate 3). At this time, the two rotating supports are in the closed state, which helps to contain the blocks and prevents the blocks from falling off the front of the trolley plate 3.
[0026] It should be noted that, since the rotating supports are located on both sides of the trolley flatbed 3 when in the open state, the width of the entire block transport trolley is extremely large, making it impossible to push and transfer it flexibly on the construction site. Therefore, in order to smoothly turn the two rotating supports to the inside of the trolley flatbed 3 by rotating the rotating handle 12, the staff actively abandoned the idea of overloading the trolley flatbed 3 with blocks, thereby avoiding the safety hazards caused by overloading the block trolley from the source.
[0027] In a specific embodiment of the present invention, in order to transmit the rotational force on the handle to the rotating stop via the transmission rod, a hinge 5 can be provided at the front end of the support sleeve 6, and the front end of the transmission rod is connected to the rotating stop via the hinge 5.
[0028] In a preferred embodiment of the present invention, the rotating support may include a rotating stop 4, a transverse stop 10, and a longitudinal stop 11, and each stop may be made of a strong supporting material such as square steel; wherein, one end of the rotating stop 4 is connected to the front end of the transmission rod via a hinge 5, the other end of the rotating stop 4 is connected to one end of the transverse stop 10, and the end of the transverse stop 10 away from the rotating stop 11 is connected to the longitudinal stop 11; and, to improve the connection stability between the stops, the rotating stop 4, the transverse stop 10, and the longitudinal stop 11 are perpendicular to each other. This arrangement allows the rotating support to have a right-angle bend shape, which better adapts to the surfaces of the block, thereby achieving stable support for the block.
[0029] It should be noted that the first section of the rotating support (i.e., the rotating stop bar 4) is connected to the hinge 5 and is perpendicular to the plane of the trolley platform. Its length is preferably 15-25cm longer than the vertical stop bar 1 or designed according to the longest side of a single block. The second section of the rotating support (i.e., the horizontal stop bar 10) is perpendicular to the first section of the rotating support and parallel to the plane of the trolley platform. Its length is designed according to the width of the trolley platform and is preferably less than half the width of the trolley platform by 15-25cm. The third section of the rotating support (i.e., the longitudinal stop bar 11) is perpendicular to the second section of the rotating support and parallel to the plane of the trolley platform. Its length is preferably 60-70cm. The second and third sections of the rotating support are on the same plane and together with the first section of the rotating support form a frame to prevent the blocks from falling during transportation.
[0030] In addition, to further improve the loading effect of the block handling trolley provided by the present invention, vertical baffles 2 can be set on both sides of the trolley flat plate 3 by welding or other means. The dimensions of the vertical baffles 2 are preferably about 80cm long and about 30cm wide. The vertical baffles 2 welded on the trolley flat plate 3 are mainly used to control the width of the block stack on the flat plate. After the trolley arrives at the stacking point, they serve as side protection on both sides of the block stack to prevent the blocks from tilting to the left or right.
[0031] In addition, several vertical baffles 1 can be fixed to the front end of the trolley flatbed 3 by welding or other means. The vertical baffles 1 welded to the front edge of the trolley flatbed 3 mainly serve two purposes: first, to regulate the number of blocks stacked, that is, to limit the number of blocks according to the length of the baffles; second, to support the weight of the block stack during transportation and removal of the block stack, so that the block stack can be placed stably on the vertical baffles 1. It should be noted that the length of the vertical baffles 1 needs to be designed according to the width of the blocks, generally 50-70cm, and its material is generally selected as threaded steel bar with a diameter of 16mm.
[0032] In one specific embodiment of the present invention, to facilitate the transportation of blocks by the block handling trolley, wheel assemblies can be provided on both sides of the trolley flatbed 3. Each wheel assembly includes an axle 9 mounted on the trolley flatbed 3 and a tire 7 connected to the axle 9. During actual installation, the axle 9 passes through a pre-drilled hole in the trolley platform and is then secured. The tire 7 is then installed on the axle 9. The tire 78 is preferably about 60cm in diameter and made of rubber. The diameter and length of the axle 9 can be designed according to the pre-drilled hole, ensuring only that the tire 7 rotates normally and meets the load-bearing requirements of the block stack.
[0033] It should be noted that in the actual production process, the trolley flatbed 3 can be made of strong supporting materials such as aluminum plates or steel plates. The preferred size is 100-120cm in length and about 60cm in width. In addition, the upper surface of the trolley flatbed 3 is provided with anti-slip grooves to increase the friction between the blocks and the platform, ensuring that the bottom blocks are placed firmly.
[0034] In the actual manufacturing process, the support sleeve 6 can be welded and fixed to the vertical baffle 2 or the trolley platform. The preferred material for the sleeve is steel tubing. The cross-sectional dimensions and length of the sleeve need to be designed according to the diameter of the transmission rod, ensuring that the transmission rod can rotate within the sleeve. In actual use, to improve the rotation effect of the transmission rod within the support sleeve 6, lubricating oil can be added to the support sleeve 6. The lubricating oil is located between the transmission rod and the inner wall of the support sleeve 6. This setting can effectively save the operator's effort when turning the rotary handle 12.
[0035] In addition, to facilitate the operation of the rotating handle 12 by the operator, the rotating handle 12 can be tilted downwards and a rubber sleeve can be fitted on the rotating handle 12 to facilitate the operation of the operator; wherein, both the transmission rod and the rotating handle 12 can be made of steel rod, and the total length of the transmission rod and the rotating handle 12 is preferably set to 180-200cm.
[0036] In addition, to ensure the smooth placement of the entire block transport trolley, a horizontal support point 7 can be fixed downwards on the support sleeve 6. The horizontal support point 7 can be welded to the bottom of the support sleeve 6. When the entire block transport trolley is stopped and placed horizontally, the horizontal support point 7 is stably supported on the ground to prevent the entire block transport trolley from sliding.
[0037] In another embodiment, the present invention also provides a method of using the aforementioned block transport trolley, the method comprising: Before transporting the blocks, rotate the handle 12 in conjunction with the transmission rod to rotate the two rotating supports 90 degrees to the sides of the trolley plate 3, so that the rotating supports are in the open state. Load and transport blocks onto the trolley flatbed 3; After the blocks to be transported are placed, rotate the rotating support 90 degrees to the inside of the trolley plate 3 by rotating the handle 12, so that the rotating support is in a closed state to enclose the blocks to be transported. Workers use block transport trolleys to transport the blocks to the preset location; once the blocks arrive at the preset location, the block transport trolleys are placed vertically on the preset material racks. By rotating the handle 12 in conjunction with the transmission rod, the two rotating supports are rotated 90 degrees to the sides of the trolley plate 3, so that the rotating supports are in the open state; then the block transport trolley is removed, and the entire load of blocks to be transported is unloaded, so that the next transport can be carried out.
[0038] Finally, it should be noted that the solution provided by the present invention provides a right-angle bent rotating support on both sides of the end of the handcart, and its end is linked with the rotating handle 12. In actual use, the operator controls the opening and closing of the support by rotating the handle 12.
[0039] Furthermore, the solution provided by this invention is an improvement on a traditional handcart, primarily used for transporting blocks. When workers transport blocks, the bent rotating support is initially kept open. After arranging and stacking the blocks, workers control the rotating support to rotate inward by 90 degrees until it closes by rotating the handle 12. This effectively controls the capacity of the handcart, preventing overloading. If blocks are overloaded, the rotating support cannot close, which significantly affects the pushing of the block transport handcart. Therefore, workers are less likely to overload blocks, effectively improving the operational safety of the block transport handcart.
[0040] Furthermore, with traditional handcarts, when stacking blocks, the front stop bar needs to be slowly pulled out from the bottom of the block pile. Some workers, due to their impatient nature or lack of safety awareness, will quickly pull out the handcart after it is placed vertically or even push it forward forcefully, trying to use inertia to send the block pile out. However, since the front stop bar and the bottom of the block are still in contact before the handcart is pulled out, there is a certain amount of friction. Pulling out the handcart too quickly or pushing it forward forcefully can easily cause the bottom of the block pile to become unbalanced and tip over due to friction. If there are workers working nearby, this could very likely cause a serious safety accident. The solution provided by this invention adds a bent-shaped rotating support to the trolley. This requires the operator to stop and open the bent-shaped rotating support before the trolley can be pulled out. During the process of the operator stopping and opening the bent-shaped rotating support, the inertia of the trolley can be effectively eliminated, and the phenomenon of the trolley being pulled out too quickly or pushed forward can be effectively prevented.
[0041] As per the above reference Figures 1 to 4 The block transport trolley according to the present invention is described by way of example. However, those skilled in the art will understand that various modifications can be made to the block transport trolley proposed in the present invention without departing from the scope of the invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
