Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for building construction, and in particular relates to a building material transport vehicle. Background Technology

[0002] During construction, building materials often need to be transferred from storage to construction site. Currently, the common methods of transfer are manual transfer or transfer carts. However, manual transfer is inefficient when it comes to transferring doors, panels, or glass. Existing transfer carts generally stack these building materials on the cart or distribute them vertically and fix them to the cart with external aids such as ropes. However, the existing transfer carts are inefficient for transferring doors, panels or glass sheets, and are prone to damaging building materials during the transfer process, resulting in defects such as scratches, dents and wear. Therefore, it is necessary to make improvements. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a building material transfer vehicle that can effectively improve the efficiency of building material transfer and reduce damage to building materials during the transfer process.

[0004] In view of this, the present invention provides a building material transfer vehicle, comprising: The vehicle body has a pushcart handle at its rear end; Wheels, wherein there are several wheels evenly distributed at the bottom of the vehicle body; Also includes: The support mechanism includes two vertical support units respectively disposed at the front and rear ends of the vehicle body, and a horizontal support unit disposed in the middle of the trolley handle; The vertical support unit and the horizontal support unit are capable of placing multiple planar plate-shaped building materials on the vehicle body in a spaced-out vertical arrangement.

[0005] In this technical solution, by combining vertical support units and horizontal support units, multiple planar plate-shaped building materials can be fixed on the vehicle body in a spaced vertical placement manner, effectively increasing the quantity of materials transported at one time; at the same time, it facilitates the quick insertion and removal of building materials, eliminating the need for cumbersome binding operations, greatly shortening loading and unloading time, and improving overall transport efficiency.

[0006] In the above technical solution, the vertical support unit further includes: A base, which is mounted on the vehicle body; A vertical support limiting plate is provided on the base and distributed parallel to the width direction of the vehicle body. Several vertical grooves are evenly distributed on the vertical support limiting plate along its own length direction. The vertical groove extends through the vertical support limiting plate along its width direction, and an opening is formed at the top of the vertical support limiting plate.

[0007] In the above technical solution, the horizontal support unit further includes: A horizontal support limiting plate is provided in the middle of the trolley handle, and a number of horizontal grooves are evenly distributed along its length. The horizontal groove extends through the horizontal support limiting plate along its height direction, and an opening is formed on the first side of the horizontal support limiting plate.

[0008] Furthermore, the above technical solution also includes: A flexible bushing is fitted in a vertical groove and a horizontal groove. The flexible bushing is U-shaped to form a groove in the middle for supporting and limiting the planar plate-shaped building material.

[0009] Furthermore, the above technical solution also includes: Adjusting blocks are detachably inserted into the inner walls of opposite sides of the flexible bushing to adjust the distance between the inner walls of opposite sides of the flexible bushing.

[0010] In the above technical solution, the wheel further includes: A wheel carrier, wherein the wheel carrier is disposed at the bottom of the vehicle body; The shock-absorbing wheel body is rotatably mounted on the wheel frame.

[0011] In the above technical solution, the shock-absorbing wheel further includes: A central hub, wherein an axle hole is formed at the center of the central hub; The outer wheel housing is fitted outside the central wheel hub and has a shock-absorbing gap between the outer wheel housing and the central wheel hub; A shock absorber arm is disposed between the central hub and the outer wheel shell to connect the central hub and the outer wheel shell. The shock absorber arm has a plurality of arms and is evenly spaced along the circumference of the central hub. The central hub and the outer wheel shell are concentrically distributed, and the shock absorber arm is S-shaped.

[0012] The beneficial effects of this utility model are: 1. Improved transfer efficiency: Through the cooperation of vertical and horizontal support units, multiple flat plate-shaped building materials can be fixed on the vehicle body in a spaced vertical placement manner, with a single transfer quantity of 5-8 pieces (far exceeding manual transfer and conventional trolleys); at the same time, the three-sided open structure of the vertical and horizontal grooves facilitates the quick insertion and removal of building materials, eliminating the need for cumbersome binding operations, greatly shortening loading and unloading time, and improving overall transfer efficiency by more than 60%.

[0013] 2. Reduce the risk of damage to building materials: The flexible bushing directly contacts the edge of the building material, using its elastic cushioning effect to avoid hard contact between the building material and the metal structure, effectively preventing scratches, dents and other damage; the adjustable bushing can be adapted to building materials of different thicknesses, ensuring that the support gap fits the size of the building material and reducing shaking during transportation; the shock-absorbing wheel of the S-shaped shock-absorbing arm can absorb the impact force of road bumps, avoiding the impact force from being transmitted to the building material and causing collision damage, reducing the building material breakage rate by more than 80%.

The transverse connecting rods are welded and fixed between the two longitudinal main beams to form a stable load-bearing plane. A push handle 2 is welded to the rear end (reverse direction) of the vehicle body 1. The push handle 2 has a U-shaped structure, including two vertical rods and a transverse grip rod. The lower end of the vertical rod is welded to the longitudinal main beam at the rear end of the vehicle body 1, and the upper end is welded to the transverse grip rod, which makes it easy for the operator to push or pull the vehicle body 1.

[0025] Wheel 3 There are 4-6 wheels, evenly distributed at the four corners of the bottom of the vehicle body 1 and on both sides of the middle of the vehicle body 1. Each wheel 3 includes a wheel frame 3 and a shock-absorbing wheel body 31. The wheel frame 3 is a conventional metal bracket, which is fixed to the bottom of the longitudinal main beam of the vehicle body 1 by bolts, and the vertical section extends downward towards the vehicle body 1. The shock-absorbing wheel body 31 is rotatably arranged between the vertical sections of the wheel frame 3, and the shock-absorbing wheel body 31 specifically includes: Center hub 310: It has a cylindrical structure and can be made of engineering plastics (such as polypropylene, polyurethane) or metal (such as aluminum alloy). It has an axle hole in the center, and a bearing (such as a deep groove ball bearing) can be installed in the axle hole. After the axle passes through the bearing, both ends are fixed to the vertical section of the wheel frame 3 to realize the rotational connection of the center hub 310. Outer wheel shell 311: It has a ring structure and is fitted on the outside of the center wheel hub 310. It is concentrically distributed with the center wheel hub 310. A shock-absorbing gap (preferably 5-10mm) is reserved between the outer wheel shell 311 and the center wheel hub 310. A rubber tire (solid tire or pneumatic tire) can be fitted on the outer periphery of the outer wheel shell 311 to enhance the friction with the ground. Shock absorber arms 312: There are 4-8 of them, evenly spaced along the circumference of the center hub 310, connecting the center hub 310 and the outer wheel shell 311. The shock absorber arms 312, the center hub 310, and the outer wheel shell 311 are integrally formed (the material is the same as the center hub 310). Specifically, they are divided into four sections: the first section extends radially outward from the circumferential outer surface of the center hub 310; the second section is an arc-shaped section, with one end connected to the outer end of the first section and the other end bending towards the center hub 310; the third section is also an arc-shaped section, with one end connected to the end of the second section and the other end bending towards the outer wheel shell 311; the fourth section extends radially inward from the circumferential inner surface of the outer wheel shell 311 and the end is connected to the end of the third section. The four sections together form an S-shaped shock absorber arm 312, which absorbs the impact force generated by road bumps by utilizing the elastic deformation of the arc-shaped section.

[0026] Supporting institutions The support mechanism includes two vertical support units 4 and one horizontal support unit 5, which can fix multiple planar plate-shaped building materials to the vehicle body 1 in a spaced-apart vertical arrangement. The specific structure is as follows: Vertical support unit 4: There are two units, which are respectively set at the front end (forward direction) and the rear end (reverse direction) of the vehicle body 1. Each vertical support unit 4 includes a base 40 and a vertical support limiting plate 41. Base 40: It is a rectangular metal plate structure, with its length direction consistent with the width direction of the vehicle body 1. The length is preferably 80-120cm, the width is preferably 15-25cm, and the thickness is preferably 3-5mm. Side baffles are vertically welded to the left and right ends of the base 40 (the two sides perpendicular to the front and rear directions of the vehicle body 1). The height of the side baffles is preferably 10-15cm, which is used to prevent building materials from slipping off the sides of the base 40. A vertical support limiting plate 41 is welded to the middle of the base 40. The base 40 is fixedly connected to the longitudinal main beam of the vehicle body 1 by welding or bolts. Vertical support limiting plate 41: It is a rectangular metal plate structure, vertically distributed upwards, with the same length as the base 40, a width preferably 8-15cm (less than the width of the base 40), and a height preferably 25-40cm; several vertical grooves 42 are evenly spaced along the length of the vertical support limiting plate 41, with a spacing of preferably 8-12cm between adjacent vertical grooves 42; the vertical grooves 42 penetrate along the width of the vertical support limiting plate 41 and form an opening at the top of the vertical support limiting plate 41, forming a groove-like structure with openings on three sides (both sides and the top side in the width direction), which facilitates the insertion and removal of building materials.

[0027] Horizontal support unit 5: Located in the middle of the trolley handle 2, including a horizontal support limiting plate 50; the horizontal support limiting plate 50 is a rectangular metal plate structure, arranged horizontally (parallel to the bearing plane of the vehicle body 1), its length is the same as the length of the vertical support limiting plate 41, its width is the same as the height of the vertical support limiting plate 41, and its height is the same as the width of the vertical support limiting plate 41; the two ends of the horizontal support limiting plate 50 in the length direction are welded and fixed to the two vertical rods of the trolley handle 2 respectively; a number of horizontal grooves are evenly spaced along the length direction of the horizontal support limiting plate 50, and the number and spacing of the horizontal grooves correspond one-to-one with the vertical grooves 42; the horizontal grooves penetrate along the height direction of the horizontal support limiting plate 50, and form an opening on the first side of the horizontal support limiting plate 50 (the side facing the first end of the vehicle body 1), which is also a groove structure with three openings (both sides in the height direction and the first side are open).

[0028] Flexible bushing 6: Sleeves inside the vertical groove 42 and the horizontal groove. The material is preferably high-elasticity wear-resistant rubber or polyurethane. The outer wall of the flexible bushing has slots 8 (three-sided slots 8, adapted to the three openings of the groove body) that mate with the vertical groove 42 / horizontal groove. The slots 8 are interconnected to form a U-shaped structure, which can be tightly locked onto the groove edge of the vertical groove 42 / horizontal groove. A U-shaped support groove is formed in the middle of the flexible bushing 6 to support and limit the edge of the flat plate building material, avoiding direct contact between the building material and the metal support and limiting plate. The flexible bushing 6 and the vertical support and limiting plate 41 / horizontal support and limiting plate 50 can be further fixed with bolts (the bolts pass through the support and limiting plate and the side wall of the slot 8 of the flexible bushing 6) to prevent the bushing from falling off during use.

[0029] Adjusting pad 7: It is detachably inserted into the inner wall of opposite sides of the flexible bushing 6, and is made of the same material as the flexible bushing 6; a T-shaped groove 9 is provided on the inner wall of the flexible bushing 6, and the T-shaped groove 9 extends along the height direction of the support groove of the flexible bushing 6, with the length consistent with the height of the support groove; a T-shaped protrusion 10 is integrally formed on one side of the adjusting pad 7 to cooperate with the T-shaped groove 9. During assembly, the T-shaped protrusion 10 is inserted into the T-shaped groove 9 to complete the fixation; by increasing or decreasing the number of adjusting pads 7 or replacing adjusting pads 7 of different thicknesses, the width of the support groove of the flexible bushing 6 can be flexibly adjusted to adapt to flat plate building materials of different thicknesses (such as 5mm thick glass, 18mm thick plywood, 40mm thick solid wood door, etc.).

[0030] Assembly and usage methods Assembly steps: Step 1: Fix the wheel frame 3 to the bottom of the longitudinal main beam of the vehicle body 1 with bolts, pass the wheel axle through the center hub 310 (with built-in bearing) of the shock-absorbing wheel body 31, and fix both ends of the wheel axle to the wheel frame 3 to complete the assembly of wheel 3; Step 2: Weld the bases 40 of the two vertical support units 4 to the transverse connecting rods at the front and rear ends of the vehicle body 1 respectively, ensuring that the length direction of the base 40 is consistent with the width direction of the vehicle body 1, and then weld the vertical support limiting plate 41 to the middle of the base 40. Step 3: Weld the horizontal support limiting plate 50 to the middle of the two vertical rods of the trolley handle 2 to ensure that the horizontal groove and the vertical groove 42 correspond one-to-one. Step 4: Align the slot 8 of the flexible bushing 6 with the edge of the vertical groove 42 / horizontal groove and snap it into place. If reinforcement is needed, screw in bolts. According to the thickness of the building material to be transported, select the corresponding size of the adjustment block 7, insert its T-shaped protrusion 10 into the T-shaped groove 9 of the flexible bushing 6, and adjust the width of the support groove to fit the thickness of the building material.

[0031] How to use: Step 1: The operator aligns the bottom edge of the flat panel building material (such as a wooden door) with the support groove of the flexible bushing 6 of the vertical support unit 4 at the front / rear end of the vehicle body 1, and inserts it vertically downwards so that the bottom of the building material is inserted into the flexible bushing 6 of the vertical groove 42. Step 2: Align the upper edge of the building material with the support groove of the flexible bushing 6 of the horizontal support unit 5, and push it in horizontally so that the upper part of the building material is inserted into the flexible bushing 6 of the horizontal groove, thus completing the fixing of a single piece of building material. Step 3: Repeat the above steps to insert multiple building materials into adjacent vertical slots 42 / horizontal slots in sequence to achieve spaced vertical placement; Step 4: The operator holds the trolley handle 2 and pushes the vehicle body 1 to move. The S-shaped shock-absorbing arm 312 of the shock-absorbing wheel 31 absorbs the impact of road bumps through elastic deformation during the journey, preventing the building materials from shaking. Step 5: After arriving at the destination, reverse the operation to remove the building materials. If it is necessary to transfer building materials of different thicknesses, the specifications or quantity of the liner 7 can be changed or adjusted, and the width of the support groove of the flexible bushing 6 can be adjusted.
