Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a rear power take-off lifting equipment. Background Technology

[0002] In recent years, the development of special-purpose vehicles has been rapid, and market demand has increased year by year, which has also promoted the development of automotive special-purpose parts manufacturing. The rear power take-off (PTO) is a power output device in a vehicle, also known as a power output unit. Existing rear PTOs include... Figure 1 As shown, the rear power take-off 100 includes a housing 110, a first mounting plate 120, a second mounting plate 130, a bearing 140, a main shaft 150, a first gear 160, and a second gear 170. The housing 110 is a tubular structure. The first mounting plate 120 is coaxially fixedly sleeved on one end of the housing 110, and the second mounting plate 130 is coaxially fixedly sleeved on the other end of the housing 110. The diameter of the first mounting plate 120 is larger than the diameter of the second mounting plate 130. The first mounting plate 120 has multiple mounting holes 121, each of which is oriented... The two mounting plates are arranged in a ring array structure. The axis of the mounting hole 121 is parallel to the axis of the first mounting plate 120. The inner side and top surface of the second mounting plate 130 form a rounded corner. The bearing 140 is disposed inside the housing 110, and the outer ring of the bearing 140 is interference-fitted with the housing 110. The main shaft 150 passes through the central hole of the bearing 140, and the main shaft 150 is interference-fitted with the inner ring of the bearing 140. The first gear 160 is coaxially fixedly connected to one end of the main shaft 150, and the second gear 170 is coaxially fixedly connected to the other end of the main shaft 150.

[0003] After the rear power take-off (PTO) is manufactured, it needs to be hoisted. Due to the special structure of the PTO, existing lifting tools (such as the small iron core lifting tool disclosed in application number 201610938485.8) are not suitable for hoisting the PTO with the above structure. When using existing lifting tools to hoist the PTO, because the shell of the PTO has a certain length, the PTO is prone to tipping to one side due to unbalanced forces, resulting in unstable hoisting. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a rear power take-off lifting device to solve the technical problem in the prior art that when lifting the rear power take-off device of the above structure, the rear power take-off device is prone to tipping to one side due to unbalanced force, resulting in unstable lifting.

[0005] To achieve the above technical objectives, the present invention provides a rear power take-off lifting device, comprising:

[0006] The seat has one end for abutting against the inner side of the first mounting plate of the rear power take-off, and the other end for abutting against the outer side and top surface of the second mounting plate of the rear power take-off.

[0007] The lifting ring is slidably connected to one end of the base and can move up and down;

[0008] A plug-in mechanism is connected to one end of the base body and is used to insert into the mounting hole of the first mounting plate;

[0009] The clamping mechanism has its middle part hinged to the seat body and one end connected to the lifting ring. During the upward movement of the lifting ring, the other end of the clamping mechanism slides from abutting against the top surface of the second mounting plate to abutting against the inner side surface of the second mounting plate, so as to cooperate with the seat body to clamp the second mounting plate.

[0010] Furthermore, one end of the base has a first abutting surface, which is a vertical surface, and the first abutting surface is used to abut against the inner surface of the first mounting plate.

[0011] Furthermore, the other end of the base has a second abutment surface, which is a vertical surface, and is used to abut against the outer side of the second mounting plate.

[0012] Furthermore, the other end of the base has a third abutment surface, which is a horizontal surface, and the third abutment surface is used to abut against the top surface of the second mounting plate.

[0013] Furthermore, the base includes a substrate, two first abutments and a second abutment. The two first abutments are disposed opposite to each other on both sides of the substrate and are fixedly connected to the bottom of one end of the substrate. The second abutment is fixedly connected to the bottom of the other end of the substrate. The sidewalls of the two first abutments away from the second abutment form the first abutment surface, and the sidewalls of the second abutment close to the two first abutments form the second abutment surface. The bottom of the other end of the substrate forms the third abutment surface.

[0014] Furthermore, a first sliding groove extending vertically is provided on one end of the seat, and the lower end of the lifting ring is slidably disposed in the first sliding groove.

[0015] Furthermore, the insertion mechanism includes two pins, one end of each pin being connected to one end of the base, and the other end of each pin being used to insert into two mounting holes of the first mounting plate.

[0016] Furthermore, one end of each of the two pins is fixedly connected to one of the two first abutments.

[0017] Furthermore, one end of the clamping mechanism that abuts against the second mounting plate forms an arcuate contact surface, so that the other end of the clamping mechanism can slide from the top surface of the second mounting plate to the inner side surface of the second mounting plate.

[0018] Furthermore, the clamping mechanism includes two clamping rods, which are disposed opposite to each other on both sides of the base. The middle of each clamping rod is hinged to the base. A second sliding groove extending along the length direction is provided on one end of each clamping rod. The lower end of the lifting ring is also slidably disposed in the two second sliding grooves. During the upward movement of the lifting ring, the other ends of the two clamping rods move downward until they are both abutting against the inner side of the first mounting plate. During the downward movement of the lifting ring, the other ends of the two clamping rods move upward until they are both released from the inner side of the first mounting plate.

[0019] Compared with the prior art, the beneficial effects of this utility model include: In use, one end of the base abuts against the inner side of the first mounting plate of the rear power take-off, and the other end of the base abuts against the outer side and top surface of the second mounting plate of the rear power take-off. The insertion mechanism is then inserted into the mounting hole of the first mounting plate. When the lifting equipment pulls the lifting ring upwards, the lifting ring moves upwards along the base. During the upward movement of the lifting ring, the other end of the abutting mechanism slides from abutting against the top surface of the second mounting plate to abutting against the inner side of the second mounting plate, thus enabling proper engagement. The base clamps the second mounting plate, thereby limiting the rear power take-off (PTO). This PTO lifting device connects to the PTO by inserting the plug-in mechanism into the mounting hole of the first mounting plate. The base and the clamping mechanism clamp the first and second mounting plates of the PTO, thus limiting the PTO and ensuring that the PTO is balanced during lifting. This prevents the PTO from tipping to one side due to unbalanced forces, ensuring the reliability of the PTO lifting. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] This utility model provides a rear power take-off lifting device, the structure of which is as follows: Figure 2 As shown, the device includes a seat 200, a lifting ring 300, a plugging mechanism 400, and a clamping mechanism 500. One end of the seat 200 is used to abut against the inner side of the first mounting plate 120 of the rear power take-off 100, and the other end is used to abut against the outer side and top surface of the second mounting plate 130 of the rear power take-off 100. The lifting ring 300 is slidably connected to one end of the seat 200 and can move up and down. The plugging mechanism 400 is connected to one end of the seat 200 and is used to insert into the mounting hole 121 of the first mounting plate 120. The middle part of the clamping mechanism 500 is hinged to the seat 200, and one end is connected to the lifting ring 300. During the upward movement of the lifting ring 300, the other end of the clamping mechanism 500 slides from abutting against the top surface of the second mounting plate 130 to abutting against the inner side of the second mounting plate 130, so as to cooperate with the seat 200 to clamp the second mounting plate 130.

[0025] In use, one end of the base 200 abuts against the inner side of the first mounting plate 120 of the rear power take-off 100, and the other end of the base 200 abuts against the outer side and top surface of the second mounting plate 130 of the rear power take-off 100. The insertion mechanism 400 is then inserted into the mounting hole 121 of the first mounting plate 120. The lifting equipment pulls the lifting ring 300 upward, and the lifting ring 300 moves upward along the base 200. As the lifting ring 300 moves upward, the other end of the clamping mechanism 500 rotates downward, and the insertion mechanism 400 continues to insert slightly into the mounting hole 121. The other end of the clamping mechanism 500 can slide from the top surface of the second mounting plate 130 to abut against the inner side of the second mounting plate 130. Then the clamping mechanism... The other end of the mechanism 500 pushes the second mounting plate 130 to the right, thereby cooperating with the seat 200 to clamp the second mounting plate 130, thus limiting the rear power take-off 100. This rear power take-off lifting device connects to the rear power take-off 100 by inserting the plug-in mechanism 400 into the mounting hole 121 of the first mounting plate 120 of the rear power take-off 100. Through the clamping of the seat 200 and the clamping mechanism 500 with the first mounting plate 120 and the second mounting plate 130 of the rear power take-off 100, the rear power take-off 100 can be limited, so that the rear power take-off 100 is balanced during the lifting process, preventing the rear power take-off 100 from tipping to one side due to unbalanced forces during the lifting process, thus ensuring the reliability of the rear power take-off 100 lifting.

[0026] As a preferred embodiment, please refer to Figure 2 One end of the seat 200 has a first abutment surface 210, which is a vertical surface. The first abutment surface 210 is used to abut against the inner side of the first mounting plate 120. When the lifting ring 300 moves upward under the action of the lifting equipment, the other end of the clamping mechanism 500 will abut against the inner side of the second mounting plate 130, thereby limiting the rear power take-off 100 and preventing the rear power take-off 100 from tipping to one side due to unbalanced force during the lifting process.

[0027] As a preferred embodiment, please refer to Figure 2The other end of the seat 200 has a second abutment surface 220, which is a vertical surface. The second abutment surface 220 is used to abut against the outer side of the second mounting plate 130. The first abutment surface 210 abuts against the inner side of the first mounting plate 120, and the second abutment surface 220 abuts against the outer side of the second mounting plate 130. When the lifting ring 300 moves upward under the action of the lifting equipment, the other end of the clamping mechanism 500 will abut against the inner side of the second mounting plate 130, thereby limiting the rear power take-off 100 and preventing the rear power take-off 100 from falling to one side due to unbalanced force during the lifting process.

[0028] As a preferred embodiment, please refer to Figure 2 The other end of the seat 200 has a third abutment surface 230, which is a horizontal surface. The third abutment surface 230 is used to abut against the top surface of the second mounting plate 130. The first abutment surface 210 abuts against the inner side of the first mounting plate 120, the second abutment surface 220 abuts against the outer side of the second mounting plate 130, and the third abutment surface 230 abuts against the top surface of the second mounting plate 130. When the lifting ring 300 moves upward under the action of the lifting equipment, the other end of the clamping mechanism 500 will abut against the inner side of the second mounting plate 130, thereby limiting the rear power take-off 100 and preventing the rear power take-off 100 from tipping to one side due to unbalanced force during the lifting process.

[0029] As a preferred embodiment, please refer to Figure 2The base 200 includes a base plate 240, two first abutments 250, and a second abutment 260. The two first abutments 250 are disposed opposite to each other on both sides of the base plate 240 and are fixedly connected to the bottom of one end of the base plate 240. The second abutment 260 is fixedly connected to the bottom of the other end of the base plate 240. The sidewalls of the two first abutments 250 away from the second abutment 260 form the first abutment surface 210, and the sidewalls of the second abutment 260 close to the two first abutments 250 form the second abutment surface 220. The bottom of the other end of the base plate 240 forms the third abutment surface 230. When hoisting the rear power take-off 100, the rear power take-off lifting device is placed on the rear power take-off 100, and the insertion mechanism 400 is inserted into the mounting hole of the first mounting plate 120. Within 121, the connection with the rear power take-off 100 is achieved. When the insertion mechanism 400 is inserted into the preset position, the sidewalls of the two first abutments 250 away from the second abutment 260 abut against the inner side of the first mounting plate 120, and the sidewalls of the second abutment 260 close to the two first abutments 250 abut against the outer side of the second mounting plate 130. The bottom of the other end of the base plate 240 abuts against the top surface of the second mounting plate 130, which can initially limit the rear power take-off 100. When the lifting ring 300 moves upward under the action of the lifting equipment, the other end of the clamping mechanism 500 will abut against the inner side of the second mounting plate 130, thereby limiting the rear power take-off 100 and preventing the rear power take-off 100 from tipping to one side due to unbalanced force during the lifting process.

[0030] As a preferred embodiment, please refer to Figure 2 The seat 200 has a first groove 270 extending vertically at one end. The lower end of the lifting ring 300 is slidably disposed in the first groove 270. The lower end of the lifting ring 300 is slidably connected to the first groove 270, thereby guiding the up and down movement of the lifting ring 300.

[0031] As a preferred embodiment, please refer to Figure 2 The first groove 270 is provided on one end of the substrate 240 to ensure that the first groove 270 can be located above the two first abutments 250. Under the action of the lifting ring 300, the other end of the abutment mechanism 500 is abutted or released against the inner side of the second mounting plate 130.

[0032] As a preferred embodiment, please refer to Figure 2 The insertion mechanism 400 includes two pins 410, one end of each pin 410 is connected to one end of the base 200, and the other end of each pin 410 is used to insert into the two mounting holes 121 of the first mounting plate 120, thereby realizing the connection with the rear power take-off 100.

[0033] As a preferred embodiment, please refer to Figure 2 One end of each of the two pins 410 is fixedly connected to one of the two first abutments 250. When the other end of each of the two pins 410 is inserted into the two mounting holes 121 of the first mounting plate 120, the two first abutments 250 will abut against the inner side of the first mounting plate 120.

[0034] As a preferred embodiment, please refer to Figure 2 The end of the clamping mechanism 500 that abuts against the second mounting plate 130 forms an arc-shaped contact surface, so that the other end of the clamping mechanism 500 can slide from the top surface of the second mounting plate 130 to the inner side surface of the second mounting plate 130, thereby clamping the inner side surface of the second mounting plate 130.

[0035] As a preferred embodiment, please refer to Figure 2 The clamping mechanism 500 includes two clamping rods 510, which are disposed opposite to each other on both sides of the base 200. The middle portions of both clamping rods 510 are hinged to the base 200. A second sliding groove 511 extending along the length of each clamping rod 510 is formed at one end. The lower end of the lifting ring 300 is slidably disposed within the two second sliding grooves 511. During upward movement of the lifting ring 300, the other ends of the two clamping rods 510 move downward until they are both abutting against the inner surface of the first mounting plate 120. During downward movement of the lifting ring 300, the other ends of the two clamping rods 510 move upward until they are both released from the inner surface of the first mounting plate 120. When the lifting ring 300 moves upward under the action of the lifting equipment, the other ends of the two clamping rods 510 rotate downward. The pin 410 will continue to be inserted slightly into the mounting hole 121. The other ends of the two clamping rods 510 can slide from the top surface of the second mounting plate 130 to abut against the inner side of the second mounting plate 130. Then, the other ends of the two clamping rods 510 will push the second mounting plate 130 to the right, thereby cooperating with the seat 200 to clamp the second mounting plate 130, thereby limiting the rear power take-off 100 and preventing the rear power take-off 100 from tipping to one side due to unbalanced force during hoisting. When the lifting ring 300 moves downward under the action of the lifting equipment, the other ends of the two clamping rods 510 move upward until they are released from the inner side of the second mounting plate 130, thereby releasing the limitation on the rear power take-off 100 and making it easier to remove the pin 410 from the mounting hole 121 of the first mounting plate 120.

[0036] In a preferred embodiment, the other end of the clamping rod 510 is provided with an anti-slip material to increase the friction between the other end of the clamping rod 510 and the inner side of the second mounting plate 130 after clamping.

[0037] As a preferred embodiment, please refer to Figure 2 Both of the clamping rods 510 are hinged to the base plate 240 at their middle parts, so that one end of the clamping rod 510 can be located above the pin 410. Under the action of the lifting ring 300, the other ends of the two clamping rods 510 can be clamped or released against the inner side of the second mounting plate 130. When the other end of the clamping rod 510 is clamped against the inner side of the second mounting plate 130, it can limit the rear power take-off 100. When the other end of the clamping rod 510 is released from the inner side of the second mounting plate 130, it is convenient for the pin 410 to be moved out of the mounting hole 121 of the first mounting plate 120.

[0038] To better understand this utility model, the following is combined with... Figure 1 - Figure 2 The working principle of the technical solution of this utility model will be described in detail below:

[0039] In use, the rear power take-off (PTO) lifting device is placed on the rear PTO 100, and the two pins 410 are respectively inserted into the two mounting holes 121 of the first mounting plate 120 of the rear PTO 100. When the pins 410 are inserted to the preset position, the sidewalls of the two first abutments 250 away from the second abutment 260 abut against the inner sidewall of the first mounting plate 120, and the sidewalls of the second abutments 260 close to the two first abutments 250 abut against the outer sidewall of the second mounting plate 130. The bottom of the other end of the base plate 240 abuts the top surface of the second mounting plate 130. The abutment provides initial restraint to the rear power take-off 100. When the lifting ring 300 moves upward under the action of the lifting equipment, the other ends of the two abutment rods 510 rotate downward, and the pin 410 continues to insert slightly into the mounting hole 121. The other ends of the two abutment rods 510 can slide from the top surface of the second mounting plate 130 to abut against the inner side of the second mounting plate 130. Then, the other ends of the two abutment rods 510 push the second mounting plate 130 to the right, thereby cooperating with the seat 200 to clamp the second mounting plate 130, thus enabling... To limit the rear power take-off 100 and prevent it from tipping to one side due to unbalanced forces during hoisting, when the lifting ring 300 moves downward under the action of the hoisting equipment, the other ends of the two clamping rods 510 will rotate upward. The other ends of the two clamping rods 510 can slide from the inner side of the second mounting plate 130 to the top surface of the second mounting plate 130, thereby releasing the limitation on the rear power take-off 100 and facilitating the removal of the pin 410 from the mounting hole 121 of the first mounting plate 120. The tool connects to the rear power take-off 100 by inserting the plug-in mechanism 400 into the mounting hole 121 of the first mounting plate 120 of the rear power take-off 100. The backing of the rear power take-off 100 by the seat 200 and the clamping mechanism 500 against the first mounting plate 120 and the second mounting plate 130 of the rear power take-off 100 can limit the rear power take-off 100, so that the rear power take-off 100 is balanced during the hoisting process, and prevents the rear power take-off 100 from tipping to one side due to the unbalanced force during the hoisting process, thus ensuring the reliability of the hoisting of the rear power take-off 100.

[0040] The rear power take-off lifting device provided by this utility model has the following beneficial effects:

[0041] (1) When the pin 410 is inserted into the preset position, the sidewalls of the two first abutments 250 away from the second abutment 260 abut against the inner sidewall of the first mounting plate 120, the sidewalls of the second abutment 260 close to the two first abutments 250 abut against the outer sidewall of the second mounting plate 130, and the bottom of the other end of the base plate 240 abuts against the top surface of the second mounting plate 130. When the lifting ring 300 moves upward under the action of the lifting equipment, the other ends of the two clamping rods 510 move downward until they abut against the inner sidewall of the second mounting plate 130, thereby limiting the rear power take-off 100.

[0042] (2) When the lifting ring 300 moves downward under the action of the lifting equipment, the other ends of the two abutting rods 510 will rotate upward. The other ends of the two abutting rods 510 can slide from the inner side of the second mounting plate 130 to the top surface of the second mounting plate 130, thereby releasing the limit on the rear power take-off 100 and making it easier to remove the pin 410 from the mounting hole 121 of the first mounting plate 120.

[0043] (3) This rear power take-off lifting device connects to the rear power take-off 100 by inserting the plug-in mechanism 400 into the mounting hole 121 of the first mounting plate 120 of the rear power take-off 100. The rear power take-off 100 is limited by the abutment of the base 200 and the abutment mechanism 500 against the first mounting plate 120 and the second mounting plate 130 of the rear power take-off 100, so that the rear power take-off 100 is balanced during the lifting process, preventing the rear power take-off 100 from tipping to one side due to unbalanced force during the lifting process, thus ensuring the reliability of the lifting of the rear power take-off 100.
