Description

Technical Field

[0001] This invention relates to the field of equipment for transferring and installing large mechanical parts, and in particular to a hydraulically lifting and repositionable handcart. Background Technology

[0002] As is known, a handcart is a device used to move heavy objects short distances by pushing and pulling them manually. A typical handcart mainly consists of a base plate and wheels at the bottom, and is also equipped with handles for pushing and pulling. In factory production practice, handcarts are usually used as transport vehicles for parts within the factory.

[0003] However, existing ordinary handcarts have limited functions. When installing some heavy parts, it is necessary to rotate them at a certain angle before installation. However, existing handcarts cannot adjust the position and angle of the parts. Moreover, heavy parts are heavy and it is difficult to adjust their position and angle manually. Therefore, it is inconvenient for workers to install heavy parts. So it is necessary to invent a hydraulic lifting and variable positioning handcart. Summary of the Invention

[0006] A speed reducer and a motor are fixedly connected to the side of the support plate near the guide rod, and a rotating platform is provided on the side of the support plate away from the guide rod; the input end of the speed reducer is driven to the output end of the motor, and the output end of the speed reducer passes through the support plate and is driven to the rotating platform.

[0007] A hydraulic cylinder is fixedly connected to the bracket. The output end of the hydraulic cylinder is connected to the housing of the reducer, which drives the reducer, motor and support plate to move up and down on the guide rod along with the slider, thereby driving the rotating table to move up and down.

[0008] Two first support rods and two second support rods are horizontally fixed on the rotating platform. The first support rods and the second support rods are symmetrically arranged to form a cage-like structure for placing parts that need to be transferred.

[0009] Multiple sets of rotating plates are fixed on the first and second support rods. Each set of rotating plates is rotatably connected to a rotating shaft. A pulley is fixed on the rotating shaft. The pulley rolls with the surface of the part being transferred, which facilitates the loading and unloading of the part being transferred. In order to prevent the part being transferred from colliding with the pulley and being worn, a rubber pad is fixedly wrapped on the surface of the pulley.

[0010] The first support rod has a connecting rod hinged to the end away from the rotating table, and a connecting plate fixed to the end of the connecting rod away from the connecting rod. The connecting plate is a U-shaped plate. The second support rod has a support plate fixed to the end away from the rotating table, and a fixed rod is rotatably connected to the support plate. A locking rod is fixed to the end of the fixed rod away from the rotating table.

[0011] The connecting rod can rotate toward the second support rod, the opening of the connecting plate faces the fixed rod, the fixed rod is inserted into the connecting plate, and the connecting plate is locked in place by the locking rod.

[0012] Furthermore, a housing is also fixedly mounted on the bracket, and the housing is also fixed to two guide rods respectively. The housing is used to enclose and protect the motor, reducer and hydraulic cylinder.

[0013] Furthermore, a switch button is provided at the top of the housing for controlling the operation of the motor and hydraulic cylinder.

[0014] Furthermore, a handle is also fixed to the surface of the housing.

[0015] Furthermore, multiple sets of rotating plates are also fixed on the connecting rod. Each set of rotating plates is rotatably connected to a rotating shaft, and a pulley is fixed on the rotating shaft.

[0016] Furthermore, a plate is fixedly connected to the end of the fixing rod away from the clamping rod, and the plate is fixedly connected to the surface of the second support rod by a spring, providing a restoring force to the fixing rod and the clamping rod.

[0017] The beneficial effects of this invention are as follows: A hydraulic lifting and variable positioning handcart allows workers to control a motor to rotate a turntable, thereby rotating heavy parts to adjust their installation angle, facilitating installation. By incorporating guide rods and sliders, the movement of the support plate can be positioned and guided during use, ensuring more stable and smooth movement. Simultaneously, the hydraulic cylinder lifts and lowers the parts, adjusting their installation position, saving workers' energy and facilitating the installation of heavy parts.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] Example 1

[0028] like Figure 1-5 The hydraulic lifting and variable positioning handcart shown includes a chassis made of two vertical rods 12, two bottom rods 13 and a bracket 21 welded together. More precisely, the frame 21 with a frame structure has two vertical rods 12 welded to each side, and bottom rods 13 welded to each of the two vertical rods 12.

[0029] like Figure 1-3 As shown, a caster wheel 14 is fixedly connected to the bottom of the vertical rod 12, and a roller is rotatably connected to the bottom rod 13; guide rods 31 are vertically fixedly installed at the ends of the two bottom rods 13 near the vertical rod 12, and two sliders 32 are slidably connected to the two guide rods 31 respectively. The sliders 32 are fixedly connected to the vertically installed support plate 15, so that the support plate 15 can slide vertically on the guide rods 31 with the sliders 32.

[0030] A reducer 16 and a motor are fixedly connected to the side of the support plate 15 near the guide rod 31, and a rotating platform 17 is provided on the side of the support plate 15 away from the guide rod 31. The input end of the reducer 16 is connected to the output end of the motor, and the output end of the reducer 16 passes through the support plate 15 and is connected to the rotating platform 17, so that the rotating platform 17 can rotate under the drive of the motor.

[0031] A hydraulic cylinder 22 is fixedly connected to the bracket 21. The output end of the hydraulic cylinder 22 is connected to the housing of the reducer 16, which drives the reducer 16, the motor and the support plate 15 to move up and down on the guide rod 31 along with the slider 32, thereby driving the rotating table 17 to move up and down.

[0032] like Figure 2-4 As shown, two first support rods 18 and two second support rods 19 are horizontally fixed on the rotating platform 17. The first support rods 18 and the second support rods 19 are symmetrically arranged to form a cage-like structure for placing parts that need to be transferred.

[0033] Multiple sets of rotating plates 51 are fixed on the first support rod 18 and the second support rod 19. Each set of rotating plates 51 is rotatably connected to a rotating shaft, and a pulley 52 is fixed on the rotating shaft. The pulley 52 rolls with the surface of the part being transferred, which facilitates the loading and unloading of the part being transferred. In order to prevent the part being transferred from colliding with the pulley 52 and being worn, a rubber pad 53 is fixedly wrapped on the surface of the pulley 52.

[0034] The first support rod 18 is hinged to a connecting rod 41 at the end away from the rotating platform 17, and a connecting plate 42 is fixedly connected to the end of the connecting rod 41 away from the connecting rod 41. The connecting plate 42 is a U-shaped plate. The second support rod 19 is fixedly connected to a support plate at the end away from the rotating platform 17. A fixing rod 43 is rotatably connected to the support plate, and a locking rod 44 is fixedly connected to the end of the fixing rod 43 away from the rotating platform 17.

[0035] The connecting rod 41 can rotate toward the second support rod 19. The opening of the connecting plate 42 faces the fixing rod 43. The fixing rod 43 is inserted into the connecting plate 42 and is secured by the locking rod 44. The longitudinal direction (axial direction) of the locking rod 44 is perpendicular to the opening direction of the connecting plate 42, so that the two ends of the locking rod 44 can be locked onto the two sides of the opening of the connecting plate 42 respectively, thereby fixing the connecting rod 41.

[0036] like Figure 1 and 2 As shown, a housing 11 is also fixedly installed on the bracket 21. The housing 11 is also fixed to two guide rods 31 respectively. The housing 11 is used to wrap and protect the motor, reducer 16 and hydraulic cylinder 22.

[0037] like Figure 1 As shown, a switch button is provided at the top of the housing 11 for controlling the operation of the motor and the hydraulic cylinder 22.

[0038] like Figure 1 As shown, a handle is also fixed to the surface of the housing 11.

[0039] like Figure 1 , 3 As shown in Figure 4, multiple sets of rotating plates 51 are also fixed on the connecting rod 41. Each set of rotating plates 51 is rotatably connected to a rotating shaft, and a pulley 52 is fixed on the rotating shaft.

[0040] like Figure 4 As shown, the end of the fixing rod 43 away from the clamping rod 44 is fixedly connected to a plate 61. The plate 61 is fixedly connected to the surface of the second support rod 19 by a spring, providing a restoring force to the fixing rod 43 and the clamping rod 44. To be precise, it is the elastic force of the spring, so that when no external force is applied, the longitudinal direction (axial direction) of the clamping rod 44 is always perpendicular to the opening direction of the connecting plate 42. Thus, the two ends of the clamping rod 44 in the longitudinal direction can be respectively clamped to the two sides of the opening of the connecting plate 42, thereby fixing the connecting rod 41.

[0041] Example 2

[0042] like Figure 5 As shown in the first embodiment, as another implementation of the present invention, a rubber sleeve 7 is fixedly attached to the surface of the grip. In use, the rubber sleeve 7 can increase the friction between the palm and the grip, while protecting the palm and reducing the squeezing between the grip and the fingers.

[0043] When using this device, heavy parts are placed between the cage-like structure formed by the first support rod 18 and the second support rod 19. Then, by pushing a trolley, the heavy parts are transported to the installation position. Afterwards, the operator can control the motor to rotate forward and reverse using the switch button on the housing 11. The motor drives the turntable 17 to rotate through the reducer 16. The motor is a servo motor. The turntable 17 drives the heavy parts to rotate, and the position and angle of the parts can be adjusted. This makes it easier for the operator to install the parts and reduces the reliance on hoisting and other forklift tools.

[0044] During use, the operator can use the hydraulic cylinder 22 to lift the reducer 16 upwards, thereby lifting the support plate 15 and the parts upwards, so as to adjust the height position and align the position of the parts with the height of the installation position, which makes it easier for the operator to install.

[0045] In use, the guide rod 31 and slider 32 can be used to position and guide the movement of the support plate 15, thereby making its movement more stable and smooth. The parts are placed on the first support rod 18 and the second support rod 19. Then, the operator can move the connecting rod 41 to align the opening of the connecting plate 42 on the connecting rod 41 with the fixed rod 43. Rotate the fixed rod 43 by about 90° so that the axial direction of the locking rod 44 is the same as the opening of the connecting plate 42, so that the fixed rod 43 is locked into the connecting plate 42. Release the fixed rod 43 so that the locking rod 44 springs back. Under the reset action of the spring, it rotates back 90°, so that the two ends of the clamping rod 44 clamp the connecting plate 42 for fixation, thereby fixing the connecting rod 41. The connecting rod 41 can limit the position of the part, making it difficult for it to slip off the first support rod 18 and the second support rod 19. By setting the pulley 52, the friction between the part and the first support rod 18, the second support rod 19 and the connecting rod 41 can be reduced, so that the workers can easily move the part onto the first support rod 18 and the second support rod 19, thus making it convenient for the workers to use.

[0046] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
