Description

Technical Field

[0001] This utility model relates to the field of motor mounting platform technology, and in particular to a mounting and fixing platform for an electric forklift pump motor. Background Technology

[0002] The pump motor is the main working component of an electric forklift. The pump motor drives the gear pump to supply oil to the hydraulic system of the electric forklift, thereby controlling the lifting, steering, and other functions of the entire vehicle. Therefore, the stability of the pump motor during operation is extremely important.

[0003] Existing technologies, such as the mounting platform for a small electric forklift pump motor disclosed in CN211841722U, include a pump motor and a platform plate. The pump motor includes a base plate, and the platform plate includes a positioning shaft and lifting rods. Two support frames are symmetrically welded to the bottom of the left and right ends of the platform plate, and two lifting rods are symmetrically welded to the middle positions of the bottom ends of the platform plate. A track shaft is welded between the middle sections of these two lifting rods, and a bidirectional threaded rod is rotatably threaded onto the collar at the tail end of the two lifting rods. In this technology, two deflection plates, four pressure rods, and two supporting shafts together form two deflection top pressure frames. These two deflection top pressure frames facilitate the implementation of the synchronous top pressure function of the four pressure rods. However, the following problems exist in use:

[0004] The above technology uses the deflection of the deflection rod to squeeze the pump motor with the pressure rod, thereby fixing the pump motor. However, during use, due to the large weight of the pump motor, the pressure rod cannot provide lateral restraint force when it shakes, making the restraint force of the pressure rod on the pump motor insufficient. This can easily cause the pump motor to detach from the side of the pressure rod, resulting in damage to the motor and malfunction of the electric forklift. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the limiting force of pump motors in the prior art is not comprehensive enough, and to propose an installation and fixing platform for electric forklift pump motors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An installation and fixing platform for an electric forklift pump motor includes a base plate and a pump motor. The base plate has a hollow structure. Four rectangular sliding grooves are formed on the upper wall of the base plate. Clamping plates for lateral limiting of the pump motor are slidably disposed in the sliding grooves. A driving mechanism for moving the clamping plates in the sliding grooves is provided inside the base plate. A fixing platform is fixedly installed on the upper wall of the base plate directly below the pump motor. A placement groove is formed in the fixing platform. A limiting mechanism for vertical limiting of the pump motor is provided in the placement groove.

[0008] Preferably, the driving mechanism includes a movable plate fixedly installed at the bottom of the clamping plate. A first slide rail is fixedly installed on the inner wall of the movable plate. A first slider in the shape of a convex shape is slidably arranged in the first slide rail. A connecting fastener in the shape of an inverted U is rotatably connected to the outer wall of the first slider through a pin. An electric telescopic rod is fixedly installed on the inner wall of the connecting fastener. A movable block is fixedly installed at the end of the electric telescopic rod. A fixing fastener is fixedly installed on the outer wall of the movable block. A connecting rod is rotatably arranged between the movable plate and the fixing fastener through a pin. A telescopic rod and a spring are fixedly installed on the inner wall of the movable block.

[0009] Preferably, the two ends of the telescopic rod and the spring are fixedly connected to the inner walls of the two movable blocks, and the telescopic rod is disposed inside the spring.

[0010] Preferably, the limiting mechanism includes a turntable rotatably mounted on the outer wall of the fixed platform, a drive gear fixedly mounted at the end of the turntable, a first rack meshing with the drive gear on the upper part of the drive gear, a second rack meshing with the drive gear on the lower part of the drive gear, a second slider fixedly mounted on the outer wall of both the first rack and the second rack, and a second slide rail on the outer wall of the second slider.

[0011] Preferably, both second slide rails are fixedly installed on the inner wall of the placement groove opened in the fixed platform. The fixed platform has through holes on both the left and right sides. The first rack is set in the through hole on the left side of the fixed platform, and the second rack is set in the through hole on the right side of the fixed platform.

[0012] Preferably, the clamping plate is inverted L-shaped and disposed in the sliding groove, and the second slider is slidably disposed in the second slide rail.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention uses four clamps that move within sliding grooves to limit the pump motor placed between the four sliding grooves, preventing the pump motor from moving laterally. Then, the movement of the first and second racks limits the pump motor, preventing it from moving vertically. This ensures that the pump motor is limited in all directions, preventing it from moving or falling off when the electric forklift is running. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 An installation and fixing platform for an electric forklift pump motor includes a base plate 1 and a pump motor 14. The base plate 1 has a hollow structure. Four rectangular sliding grooves 4 are provided on the upper wall of the base plate 1. Clamping plates 3 for lateral limiting of the pump motor 14 are slidably arranged in the sliding grooves 4. A driving mechanism for driving the clamping plates 3 to move in the sliding grooves 4 is provided in the base plate 1. A fixing platform 15 is fixedly installed on the upper wall of the base plate 1 directly below the pump motor 14. A placement groove is provided in the fixing platform 15. A limiting mechanism for vertical limiting of the pump motor 14 is provided in the placement groove.

[0023] The driving mechanism includes a movable plate 2 fixedly installed at the bottom of the clamping plate 3. A first slide rail 5 is fixedly installed on the inner wall of the movable plate 2. A first slider 6 in the shape of a convex shape is slidably arranged in the first slide rail 5. A connecting fastener 7 in the shape of a chamfer is rotatably connected to the outer wall of the first slider 6 through a pin. An electric telescopic rod 8 is fixedly installed on the inner wall of the connecting fastener 7. A movable block 9 is fixedly installed at the end of the electric telescopic rod 8. A fixing fastener 11 is fixedly installed on the outer wall of the movable block 9. A connecting rod 10 is rotatably arranged between the movable plate 2 and the fixing fastener 11 through a pin. A telescopic rod 12 and a spring 13 are fixedly installed on the inner wall of the movable block 9.

[0024] It should be noted that, as shown in the attached document... Figure 3As shown, when the connecting rod 10 pushes the two movable blocks 9 to move towards each other, the movable blocks 9 will synchronously drive the electric telescopic rod 8 to move, so that the electric telescopic rod 8 synchronously drives the first slider 6 to slide within the first slide rail 5.

[0025] The telescopic rod 12 and the spring 13 are fixedly connected at both ends to the inner walls of the two movable blocks 9, and the telescopic rod 12 is located inside the spring 13.

[0026] It should be noted that when the two movable blocks 9 move toward each other, the telescopic rod 12 ensures that the moving directions of the two movable blocks 9 are always opposite, and the spring 13 facilitates the two movable blocks 9 to move toward each other, making the movement of the two movable blocks 9 more stable.

[0027] The limiting mechanism includes a turntable 16 rotatably mounted on the outer wall of the fixed platform 15. A drive gear 17 is fixedly mounted at the end of the turntable 16. A first rack 18 is provided on the upper part of the drive gear 17 and meshes with the drive gear 17. A second rack 19 is provided on the lower part of the drive gear 17 and meshes with the drive gear 17. A second slider 20 is fixedly mounted on the outer wall of both the first rack 18 and the second rack 19. A second slide rail 21 is provided on the outer wall of the second slider 20.

[0028] Both second slide rails 21 are fixedly installed on the inner wall of the placement groove opened in the fixed platform 15. The fixed platform 15 has through holes on both the left and right sides. The first rack 18 is set in the through hole on the left side of the fixed platform 15, and the second rack 19 is set in the through hole on the right side of the fixed platform 15.

[0029] The clamping plate 3 is inverted L-shaped and is set in the sliding groove 4, and the second slider 20 is slidably set in the second slide rail 21.

[0030] The functional principle of this utility model can be explained through the following operation methods:

[0031] By placing the pump motor 14 within the plane enclosed by the four sliding grooves 4, and then activating the electric telescopic rod 8, the electric telescopic rod 8 pulls the connecting fastener 7 towards the movable block 9. The connecting fastener 7 then pulls the first slide rail 5, causing the first slide rail 5 to pull the moving plate 2 towards the movable block 9. When both moving plates 2 move towards the movable block 9 simultaneously, the distance between the two moving plates 2 decreases, causing the connecting rod 10 to push the two movable blocks 9 towards each other, further reducing the distance between the two movable blocks 9. Then, the two movable blocks 9 compress the spring 13 and the telescopic rod 12. When the moving plate 2... When the movable clamping plate 3 slides in the sliding groove 4 until it is in contact with the pump motor 14, the electric telescopic rod 8 is closed, causing the clamping plate 3 to stop moving and the pump motor 14 to be laterally limited. Then, the turntable 16 is rotated, causing the turntable 16 to drive the drive gear 17 to rotate. The drive gear 17 drives the first rack 18 located on the upper part of the drive gear 17 and the second rack 19 located on the lower part of the drive gear 17 to move towards each other. The first rack 18 slides to the left on the second slide rail 21, and the second rack 19 slides to the right on the second slide rail 21, thereby vertically limiting the pump motor 14 and fixing the pump motor 14.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
