Description

Technical Field

[0001] This utility model relates to the field of building material trolley technology, and in particular to a small trolley for hoisting building floor materials. Background Technology

[0002] A crane trolley is a special vehicle that combines lifting and transportation functions, often referred to as a truck-mounted crane or crane transport vehicle. This type of vehicle uses a hydraulic lifting system mounted on a truck chassis to achieve the lifting, rotating, and transporting of goods.

[0003] Existing technologies, such as the one disclosed in CN222744019U, describe a grinding roller lifting trolley for easy hoisting. This trolley includes a main body with a base plate fixedly mounted on its top outer surface. Multiple sets of grinding rollers are movably mounted between several sets of limiting plates. Two sets of outer shells are fixedly mounted on the outer surfaces of each of the limiting plates. Two sets of fixing seats are fixedly mounted on the inner walls of each of the two sets of outer shells. A circular through-slot is formed on the outer surface of each fixing seat. A lead screw is movably mounted in the circular through-slot, with one end of the lead screw connected to a motor. A push rod is movably mounted on the outer surface of the lead screw. This invention uses a motor to drive the lead screw to rotate, and the push rod precisely lifts the grinding rollers to a suitable height, preventing the rollers from remaining parallel and effectively avoiding collisions between the lifting fixture and the grinding rollers. This design reduces potential risks during hoisting and improves operational safety.

[0004] To address the issue of material accumulation on existing trolleys, which have a fixed capacity, when there are many items, some will fall off the trolley, requiring secondary transport and retrieval, which is inconvenient. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing trolleys have a fixed capacity for placing objects, and when there are many objects, the objects will fall off the trolley, requiring secondary transportation and lifting, which is inconvenient. Therefore, a trolley for lifting building floor materials is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a trolley for hoisting building floor materials, comprising a base plate, wheels, a support plate, a push rod, and an extension device. The wheels are fixedly connected to the lower surface of the base plate, the support plate is fixedly connected to the upper surface of the base plate, and the push rod is fixedly connected to the surface of the base plate. The base plate is provided with a locking groove and a sliding groove, which are formed on the surface of the base plate. The extension device is disposed on the surface of the locking groove and includes an extension plate that is slidably connected to the inner wall of the locking groove. A hook is fixedly connected to the upper surface of the extension plate, and a connecting block is disposed on the outer side of the support plate.

[0007] Furthermore, the number of the sliding grooves is eight, and the surface of the extension plate is fixedly connected with sliding rods, the number of which is eight, and the sliding rods are slidably connected to the inner wall of the sliding grooves.

[0008] Furthermore, a connecting block is fixedly connected to the surface of the sliding rod, and a column is fixedly connected to the upper surface of the base plate. The number of columns is four and they are arranged symmetrically.

[0009] Furthermore, a long rod is fixedly connected to the lower surface of the connecting block, the long rod is slidably connected to the inner wall of the column, a limit groove is formed on the surface of the column, a limit block is fixedly connected to the surface of the long rod, and the limit block is slidably connected to the inner wall of the limit groove.

[0010] Furthermore, a fixing device is provided on the surface of the support plate, the fixing device including an L-shaped block, the L-shaped block being fixedly connected to the surface of the support plate, and a return spring being fixedly connected to the surface of the L-shaped block.

[0011] Furthermore, the end of the return spring away from the L-shaped block is fixedly connected to the surface of the pull rod, and a fixing hole is provided on the surface of the L-shaped block.

[0012] Furthermore, a plug is fixedly connected to the surface of the pull rod, and the plug is sleeved and connected to the inner wall of the fixing hole. The surface of the extension plate is provided with positioning holes, and the number of positioning holes is multiple and arranged in an array. The plug is inserted and connected to the inner wall of the positioning hole.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an extension device, the support plate can be extended and lengthened, making the use of the extension plate more convenient. Lifting the extension plate allows it to slide along the inner wall of the locking groove, causing the extension plate to drive the sliding rod to move stably upwards along the inner wall of the sliding groove. Then, the connecting block drives the long rod to move stably upwards along the inner wall of the column. The sliding of the limiting block between the limiting grooves prevents the long rod from detaching from the inner wall of the column. By setting an extension device, the support plate can be extended and lengthened, avoiding the problem that existing trolleys have a fixed capacity for placing objects. When there are many objects, they may fall off the trolley, requiring secondary transportation and lifting, which is inconvenient. This effectively improves the practicality of the equipment.

[0015] 2. In this utility model, by setting a fixing device, the height of the extension plate is easily fixed, making the overall use of the device more convenient. To this end, pulling the pull rod causes the insertion rod to disengage from the inner wall of the positioning hole, causing the return spring to be stretched and expanded under force. Then, the height position of the extension plate is adjusted, and then the pull rod is released, causing the return spring to rebound after being unrestrained, so that the insertion rod is inserted into the inner wall of the corresponding positioning hole, thus fixing the extension plate. By setting a fixing device, the height of the extension plate is easily fixed, avoiding the extension plate from becoming loose and thus effectively improving the stability of the equipment.

[0023] Please see Figures 1-5This utility model provides a technical solution: a trolley for hoisting building floor materials, including a base plate 1, wheels 2, a support plate 3, a push rod 4 and an extension device 5. The wheels 2 are fixedly connected to the lower surface of the base plate 1, the support plate 3 is fixedly connected to the upper surface of the base plate 1, the push rod 4 is fixedly connected to the surface of the base plate 1, the base plate 1 is provided with a locking groove 51 and a sliding groove 54, the locking groove 51 and the sliding groove 54 are opened on the surface of the base plate 1, and the extension device 5 is disposed on the surface of the locking groove 51.

[0024] The specific setup and function of the extension device 5 and the fixing device 6 will be explained in detail below.

[0025] In this embodiment: the extension device 5 includes an extension plate 52, which is slidably connected to the inner wall of the engagement groove 51, and a hook ring 53 is fixedly connected to the upper surface of the extension plate 52.

[0026] Specifically, there are eight sets of slide grooves 54, and slide rods 55 are fixedly connected to the surface of the extension plate 52. There are eight sets of slide rods 55, and the slide rods 55 are slidably connected to the inner wall of the slide groove 54.

[0027] Specifically, a connecting block 56 is fixedly connected to the surface of the slide bar 55. The connecting block 56 is located on the outside of the support plate 3. A column 57 is fixedly connected to the upper surface of the base plate 1. There are four sets of columns 57 arranged symmetrically.

[0028] Specifically, a long rod 58 is fixedly connected to the lower surface of the connecting block 56. The long rod 58 is slidably connected to the inner wall of the column 57. A limiting groove 59 is opened on the surface of the column 57. A limiting block 510 is fixedly connected to the surface of the long rod 58. The limiting block 510 is slidably connected to the inner wall of the limiting groove 59.

[0029] The effects achieved by the above components are as follows: by setting the locking groove 51, it is easy to accommodate the extension plate 52; by setting the sliding groove 54 and the sliding rod 55, it is easy for the extension plate 52 to move vertically and stably along the inner wall of the locking groove 51; by setting the connection between the column 57 and the long rod 58, it is easy to prevent the extension plate 52 from getting stuck during the lifting and lowering process; and by setting the connection between the limiting block 510 and the limiting groove 59, it is easy to prevent the extension plate 52 from separating from the inner wall of the locking groove 51.

[0030] Specifically, a fixing device 6 is provided on the surface of the support plate 3. The fixing device 6 includes an L-shaped block 61, which is fixedly connected to the surface of the support plate 3. A return spring 62 is fixedly connected to the surface of the L-shaped block 61.

[0031] Specifically, the end of the return spring 62 away from the L-shaped block 61 is fixedly connected to the surface of the pull rod 63, and the surface of the L-shaped block 61 is provided with a fixing hole 64.

[0032] Specifically, the surface of the pull rod 63 is fixedly connected to the insertion rod 65, the insertion rod 65 is sleeved and connected to the inner wall of the fixing hole 64, and the surface of the extension plate 52 is provided with positioning holes 66. The number of positioning holes 66 is multiple and they are arranged in an array. The insertion rod 65 is inserted and connected to the inner wall of the positioning hole 66.

[0033] The effect achieved by the above components is as follows: by setting a return spring 62, after the pull rod 63 is unrestrained, the rebound force of the return spring 62 can drive the insertion rod 65 to move. The connection between the insertion rod 65 and the positioning hole 66 makes it easy for the insertion rod 65 to fix the position of the extension plate 52, and prevents the objects placed in the support plate 3 from falling off due to the unfixed position of the extension plate 52.

[0034] Working principle: By setting up the extension device 5, the support plate 3 can be extended and lengthened, making the use of the extension plate 52 more convenient. Lifting the extension plate 52 causes it to slide along the inner wall of the locking groove 51, which in turn drives the sliding rod 55 to move steadily upward along the inner wall of the sliding groove 54. Then, the connecting block 56 drives the long rod 58 to move steadily upward along the inner wall of the column 57. The sliding of the limiting block 510 along the limiting groove 59 prevents the long rod 58 from detaching from the inner wall of the column 57. By setting up the extension device 5, the support plate 3 can be extended and lengthened, avoiding the fixed capacity of the existing trolley. When there are many objects, they will fall off the trolley, requiring secondary transportation and lifting, which is inconvenient. This effectively improves the practicality of the equipment.

[0035] Furthermore, by setting up the fixing device 6, the height of the extension plate 52 can be easily fixed, making the overall use of the device more convenient. To do this, pull the pull rod 63 to disengage the insertion rod 65 from the inner wall of the positioning hole 66, causing the return spring 62 to be stretched and expanded under force. Then, adjust the height position of the extension plate 52, and then release the pull rod 63, causing the return spring 62 to rebound after being unrestrained, so that the insertion rod 65 is inserted into the inner wall of the corresponding positioning hole 66, thus fixing the extension plate 52. By setting up the fixing device 6, the height of the extension plate 52 can be easily fixed, preventing the extension plate 52 from becoming loose and thus effectively improving the stability of the equipment.
