Description

Technical Field

[0001] The present invention relates to the technical field of jacks, and more specifically, to a wedge-shaped hydraulic jack. Background Art

[0002] A hydraulic jack, also known as an oil jack, is a jack that uses a plunger or hydraulic cylinder as a rigid lifting member. A simple lifting device generally only has a lifting mechanism for lifting heavy objects. It has a simple structure, is light in weight, easy to carry, and convenient to move. Common simple lifting devices include hydraulic jacks, pulleys, and winches, etc.

[0003] Among them, the patent with publication number CN213595763U discloses a portable hydraulic jack, which relates to the field of hydraulic jacks. It includes a chassis. A groove cover is provided on the end face of the chassis, and a placement box is fixed on one side of the chassis. A handle is provided at the top of the placement box, and a hydraulic jack is installed inside the placement box at the top of the chassis. A push rod is provided at the top of the hydraulic jack, and a rubber pad is provided at the top of the push rod. A hydraulic component connected to the hydraulic jack is installed at the top of the chassis on one side of the hydraulic jack, and a pedal is provided at one end of the hydraulic component. A fixed claw is provided on one side of the chassis;

[0004] When this structure is in use, by setting the placement box, handle, fixed rod, wedge-shaped rod, and return spring, the problem that the hydraulic jack is inconvenient to carry is solved. By setting the pedal, fixed claw, storage groove, and groove cover, the problem of lacking a chassis limiting mechanism is solved. However, this structure is suitable for use in a relatively small space when in use, resulting in limitations in the use of the device. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wedge-shaped hydraulic jack, aiming to solve the problems proposed in the above background art.

[0006] The present invention provides the following technical solutions: A wedge-shaped hydraulic jack includes a base, and a lifting assembly is provided on the base;

[0007] The lifting assembly includes a reinforced sealed transfer frame arranged in the middle of the base. A guide cylinder is provided on one side of the reinforced sealed transfer frame. The reinforced sealed transfer frame is communicated with the guide cylinder. A telescopic rod is slidably connected in the guide cylinder, and a limit pin is sleeved at one end of the telescopic rod;

[0008] The base is provided with a reinforced triangular lifting block with adjustable angle. Both ends of the limit pin are rotatably connected with a traction rod body, and one end of each traction rod body extends to the bottom of the reinforced triangular lifting block and is rotatably connected with the reinforced triangular lifting block;

[0009] The vertical cross-section of the reinforced triangular lifting block is set to a triangle, and a rotating rod is embedded in one end of the reinforced triangular lifting block, and the rotating rod is rotatably connected to the reinforced triangular lifting block. A limiting sleeve is fixedly provided on both sides of the base, and a rotating shaft is rotatably connected in the limiting sleeve, and the rotating shaft is fixedly provided on the reinforced triangular lifting block.

[0010] It can be seen that in the above technical solution, when the extension rod is extended, it will drive the limit pin to move, thereby enabling the traction rod body to pull the reinforced triangular lifting block to deflect along the axial center point of the connection between the rotating shaft and the limit sleeve, thereby enabling the reinforced triangular lifting block to be tilted and lifted.

[0011] Optionally, in a possible embodiment, a hydraulic cylinder body is provided on one side of the surface of the base, a handle is hinged on the hydraulic cylinder body, a regulating valve is provided at one end of the hydraulic cylinder body, the regulating valve is communicated with the hydraulic cylinder body, a valve stem body for flow regulation is rotatably connected to the regulating valve, a first reinforced delivery pipe is provided on the regulating valve, a second reinforced delivery pipe is provided on the top of the first reinforced delivery pipe, the first reinforced delivery pipe and the second reinforced delivery pipe are both communicated with the regulating valve, the first reinforced delivery pipe and the second reinforced delivery pipe extend to the reinforced sealing transfer frame at one end away from the regulating valve, and two through holes are provided on the outer side of the reinforced sealing transfer frame that are respectively communicated with the first reinforced delivery pipe and the second reinforced delivery pipe;

[0012] It can be seen that in the above technical solution, repeatedly turning the handle allows the oil in the hydraulic cylinder to be transported to the first reinforced delivery pipe through the regulating valve, and the oil is transported to the reinforced sealing transfer frame and the guide cylinder through the first reinforced delivery pipe, so that the extension rod can be extended along the guide of the guide cylinder, and the flow rate of the oil transported to the regulating valve through the hydraulic cylinder body can be adjusted through the valve stem body, which makes it easy to fine-tune the stroke of the reinforced triangular lifting block when lifting, thereby improving the accuracy of the workpiece lifting.

[0013] Optionally, in a possible embodiment, a reinforced deflection plate with an adjustable angle is hinged on one side of the top of the base, the reinforced deflection plate is located on the top of the reinforced sealing transfer frame, a driving motor is installed on the reinforced deflection plate by bolts, the output end of the driving motor is installed with a first gear through a coupling, a supporting swivel is provided on the top of the reinforced sealing transfer frame, a second gear is rotatably connected to the supporting swivel, the second gear is meshed with the first gear, a screw rod is clamped in the middle of the second gear, the screw rod passes through the supporting swivel and extends into the reinforced sealing transfer frame, the screw rod is rotatably connected to the support swivel, and the outer side of the screw rod is threadedly connected to a sealing baffle, and the sealing baffle is slidably connected to the reinforced sealing transfer frame;

[0014] It can be seen that in the above technical solution, when the screw rotates, the sealing baffle will be displaced up and down in the reinforced sealing transfer frame due to the traction force when the screw rotates, thereby realizing the function of adjusting the position of the sealing baffle, and when the sealing baffle is displaced, it will respectively fit with the through holes at one end of the first reinforced delivery pipe and the second reinforced delivery pipe to seal them, so that when the sealing baffle is easily transferred to the through hole at one end of the first reinforced delivery pipe, the oil in the reinforced sealing transfer frame and the guide cylinder can be returned to the second reinforced delivery pipe through the through hole at one end of the second reinforced delivery pipe, which is convenient for resetting the reinforced triangular lifting block, and the first reinforced delivery pipe and the second reinforced delivery pipe are sealed by displacing the sealing baffle, which can effectively avoid the phenomenon of oil backflow during transportation, thereby ensuring the stability of the reinforced triangular lifting block when supporting the workpiece.

[0015] The technical effects and advantages of the present invention are as follows:

[0016] 1. The present invention repeatedly moves the handle to allow the oil in the hydraulic cylinder to be transported through the regulating valve to the first reinforced delivery pipe, and then the oil is transported through the first reinforced delivery pipe to the reinforced sealing transfer frame and the guide cylinder, so that the extension rod can be extended along the guide of the guide cylinder. When the extension rod is extended, it will drive the limit pin to move, and then the traction rod body pulls the reinforced triangular lifting block to deflect along the axis point of the connection between the rotating shaft and the limit sleeve, thereby allowing the reinforced triangular lifting block to tilt and lift, thereby realizing the function of lifting the workpiece;

[0017] 2. The present invention adjusts the flow rate of oil delivered to the regulating valve through the hydraulic cylinder via the valve stem, making it easy to fine-tune the stroke of the reinforced triangular jacking block during jacking, thereby improving the accuracy of workpiece jacking. In addition, the setting of the rotating rod facilitates the insertion of the reinforced triangular jacking block between two workpieces, reducing the friction between the end of the reinforced triangular jacking block and the workpiece.

[0018] 3. In the present invention, when the sealing baffle is displaced, it fits in contact with the through-holes at one end of the first reinforced delivery pipe and the second reinforced delivery pipe to seal them. When the sealing baffle is transferred to the through-hole at one end of the first reinforced delivery pipe, the oil in the reinforced sealing transfer frame and the guide cylinder can be returned to the second reinforced delivery pipe through the through-hole at one end of the second reinforced delivery pipe, thereby facilitating the reset of the reinforced triangular lifting block.

[0019] 4. When the second gear of the present invention rotates, it drives the screw to rotate in the support swivel. When the screw rotates, the sealing baffle is displaced up and down in the reinforced sealing transfer frame by the traction force of the screw rotation, thereby achieving the function of adjusting the position of the sealing baffle. The first and second reinforced conveying pipes are blocked by the displacement of the sealing baffle, which can effectively prevent the backflow of oil during delivery and ensure the stability of the reinforced triangular lifting block when supporting the workpiece;

[0020] In summary, the overall design is simple and the structure is reasonable. Through the coordinated use of each structure, when the extension rod extends, it will drive the displacement of the limit pin, and then the traction rod body will pull the reinforced triangular lifting block to deflect along the axis point of the connection between the rotating shaft and the limit sleeve. Then the reinforced triangular lifting block can be tilted up, thus realizing the function of lifting the workpiece. The flow rate of the oil passing through the hydraulic cylinder body to the regulating valve is adjusted by the valve rod body, which is easy to finely adjust the stroke when the reinforced triangular lifting block is lifted, improving the accuracy when the workpiece is lifted. The sealing baffle moves up and down in the reinforced sealing transfer frame under the traction force when the screw rod rotates, realizing the function of adjusting the position of the sealing baffle. By blocking the first reinforced delivery pipe and the second reinforced delivery pipe through the displacement of the sealing baffle, the phenomenon of oil backflow during delivery can be effectively avoided, ensuring the stability when the reinforced triangular lifting block supports the workpiece.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] As shown in the attached Figure 1 - Figure 8 For a wedge-shaped hydraulic jack shown, through the lifting assembly provided on the base 1, through the corresponding cooperation of each structure, when the extension rod 4 extends, it will drive the displacement of the limit pin 5, and then the traction rod body 7 will pull the reinforced triangular lifting block 6 to deflect along the center point of the connection between the rotating shaft 23 and the limit sleeve 22, and then the reinforced triangular lifting block 6 can be tilted to lift, thereby realizing the function of lifting the workpiece. The flow rate of the oil passing through the hydraulic cylinder body 9 and conveyed to the regulating valve 11 is adjusted through the valve rod body 12, which is easy to finely adjust the stroke when the reinforced triangular lifting block 6 is lifted, improving the accuracy when the workpiece is lifted. The sealing baffle 21 moves up and down in the reinforced sealing transfer frame 2 under the traction force when the lead screw 19 rotates, realizing the function of adjusting the position of the sealing baffle 21. By blocking the first reinforced conveying pipe 13 and the second reinforced conveying pipe 14 in the way of the displacement of the sealing baffle 21, the phenomenon of oil backflow during transportation can be effectively avoided, ensuring the stability when the reinforced triangular lifting block 6 supports the workpiece, and the specific structure of the assembly is as follows;

[0033] The lifting assembly includes a reinforced sealing transfer frame 2 provided in the middle of the base 1. A guide cylinder 3 is provided on one side of the reinforced sealing transfer frame 2. The reinforced sealing transfer frame 2 is communicated with the guide cylinder 3. An extension rod 4 is slidably connected in the guide cylinder 3, and a limit pin 5 is sleeved at one end of the extension rod 4;

[0034] An angle-adjustable reinforced triangular lifting block 6 is provided on the base 1. Both ends of the limit pin 5 are rotatably connected to a traction rod body 7, and one end of each traction rod body 7 extends to the bottom of the reinforced triangular lifting block 6 and is rotatably connected to the reinforced triangular lifting block 6.

[0035] The vertical cross-section shape of the reinforced triangular lifting block 6 is set to be a triangle, and a rotating rod 8 is embedded in one end of the reinforced triangular lifting block 6, and the rotating rod 8 is rotatably connected to the reinforced triangular lifting block 6. A limiting sleeve 22 is fixedly provided on both sides of the base 1, and a rotating shaft 23 is rotatably connected in the limiting sleeve 22, and the rotating shaft 23 is fixedly provided on the reinforced triangular lifting block 6.

[0036] A hydraulic cylinder body 9 is provided on one side of the surface of the base 1, and a handle 10 is hinged on the hydraulic cylinder body 9. A regulating valve 11 is provided at one end of the hydraulic cylinder body 9. The regulating valve 11 is connected to the hydraulic cylinder body 9. A valve stem body 12 for flow regulation is rotatably connected to the regulating valve 11. A first reinforced delivery pipe 13 is provided on the regulating valve 11. A second reinforced delivery pipe 14 is provided on the top of the first reinforced delivery pipe 13. The first reinforced delivery pipe 13 and the second reinforced delivery pipe 14 are both connected to the regulating valve 11. The first reinforced delivery pipe 13 and the second reinforced delivery pipe 14 extend to the reinforced sealing transfer frame 2 at one end away from the regulating valve 11, and two through holes 24 are provided on the outside of the reinforced sealing transfer frame 2 that are respectively connected to the first reinforced delivery pipe 13 and the second reinforced delivery pipe 14;

[0037] A reinforced deflector plate 15 with adjustable angle is hinged on one side of the top of the base 1. The reinforced deflector plate 15 is located at the top of the reinforced sealing transfer frame 2. A drive motor 16 is installed on the reinforced deflector plate 15 by bolts. The output end of the drive motor 16 is installed with a first gear 17 through a coupling. A support swivel 18 is provided at the top of the reinforced sealing transfer frame 2. A second gear 20 is rotatably connected to the support swivel 18. The second gear 20 is engaged with the first gear 17. A screw rod 19 is clamped in the middle of the second gear 20. The screw rod 19 passes through the support swivel 18 and extends into the reinforced sealing transfer frame 2. The screw rod 19 is rotatably connected to the support swivel 18, and the outer side of the screw rod 19 is threadedly connected to a sealing baffle 21. The sealing baffle 21 is slidably connected to the reinforced sealing transfer frame 2.

[0038] According to the above structure, when using, the staff installs the device at the designated position. When the workpiece needs to be lifted, one end of the reinforced triangular lifting block 6 is inserted between the two workpieces. The handle 10 is repeatedly turned to allow the oil in the hydraulic cylinder 9 to be transported to the first reinforced delivery pipe 13 through the regulating valve 11. The oil is then transported to the reinforced sealing transfer frame 2 and the guide cylinder 3 through the first reinforced delivery pipe 13, so that the extension rod 4 can be extended along the guide of the guide cylinder 3.

[0039] When the extension rod 4 is extended, the limit pin 5 is displaced, and the traction rod body 7 is pulled to pull the reinforced triangular lifting block 6 to deflect along the axis point where the rotating shaft 23 and the limit sleeve 22 are connected, thereby enabling the reinforced triangular lifting block 6 to be tilted and lifted;

[0040] At the same time, when the device is in use, the flow rate of the oil delivered to the regulating valve 11 through the hydraulic cylinder 9 can be adjusted through the valve stem body 12, which makes it easy to fine-tune the stroke of the reinforced triangular jacking block 6 when jacking up, thereby improving the accuracy of the workpiece jacking;

When the screw 19 rotates, the sealing baffle 21 is displaced up and down in the reinforced sealing transfer frame 2 due to the traction force of the screw 19 when rotating, thereby achieving the function of adjusting the position of the sealing baffle 21;

[0042] When the sealing baffle 21 is displaced, it will fit in with the through holes 24 at one end of the first reinforced delivery pipe 13 and the second reinforced delivery pipe 14 to seal them. When the sealing baffle 21 is transferred to the through hole 24 at one end of the first reinforced delivery pipe 13, the oil in the reinforced sealing transfer frame 2 and the guide cylinder 3 can be returned to the second reinforced delivery pipe 14 through the through hole 24 at one end of the second reinforced delivery pipe 14, which facilitates the reset of the reinforced triangular lifting block 6.

[0043] Furthermore, the first reinforced delivery pipe 13 and the second reinforced delivery pipe 14 are blocked by displacing the sealing baffle 21, which can effectively prevent the oil from flowing back during delivery and ensure the stability of the reinforced triangular lifting block 6 when supporting the workpiece.

[0044] When the jack is lifted up, the workpiece is lifted up and the workpiece is lifted up, and the workpiece is lifted up and the workpiece is lifted up. When the jack is lifted up, the workpiece is lifted up and the workpiece is lifted up, and the workpiece is lifted up and the workpiece is lifted up, the workpiece is lifted up and the workpiece is lifted up. When the jack is lifted up, the workpiece is lifted up and the workpiece is lifted up, the workpiece is lifted up and the workpiece is lifted up. When the jack is lifted up, the workpiece is lifted up and the workpiece is lifted up, the workpiece is lifted up and the workpiece is lifted up, and ...
