Description

TECHNICAL FIELD

[0001] The utility model relates to self -balancing height adjusting positioning device technical field especially relates to novel hydraulic self -balancing parking device. BACKGROUND

[0002] Common self -balancing height adjusting positioning device, one is through spring and pulley gravity balance system construction inside, often the mechanical components involved are more, complex structure, bulky, usually applied to the height adjustment self -balancing positioning of heavy equipment.

[0003] Another is through the realization of hydraulic transmission principle and is used for the self -balancing height adjusting device of light -duty equipment, and two hydraulic cavities in its interior are through the installation rubber bowl between piston slider and cylinder wall shell to realize movement and static sealing, and when the pressure of two hydraulic cavities is unbalanced, the pressure difference drives the rubber sealing plug on the slider to act to unseal, opens the passageway and makes the hydraulic medium in two cavities flow to make the piston slider move and drive the spindle integrated with the piston slider to move to adjust the height, and then is static in the balance position. Since the movement sealing between the shell and the slider is mainly realized by the rubber bowl and the O-ring, the rubber bowl is relatively large in size, and reverse, scratching and other phenomena may occur during assembly. In order to make the rubber sealing plug open the hydraulic medium flow channel in time when there is a pressure difference, it is designed to be in a relatively free movement state at the opening, and completely relies on the pressure difference to press the sealing and disengage, lacking the necessary movement guide design, so that the action of opening and closing the channel is not sensitive or misoperation. In addition, the use of a large number of rubber seals inside the sealing requires higher surface quality of the matched parts, higher processing cost, and higher purity of the hydraulic medium. Lower part surface quality and medium particles can damage the rubber sealing performance, so that the positioning cannot be stable for a long time, and the aging of a large number of rubber seals can also cause positioning failure, thereby reducing the reliability of the device. Therefore, the novel hydraulic self -balancing parking device is proposed. CONTENT OF THE UTILITY MODEL

[0041] (4) The small hole damper limits the flow rate of hydraulic oil through the small hole, generates damping effect, avoids impact caused by rapid movement of the slider assembly, makes the height adjustment process stable and controllable, is especially suitable for positioning requirements of precision equipment or sensitive load, and automatically locks the locking mechanism under the action of spring force after the hydraulic oil pressure in the upper and lower cavities is balanced, prevents positioning failure caused by accidental external force or vibration, and improves the safety and reliability of the device in the static state.

[0061] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the utility model.

[0062] Please refer to Figures 1-9The embodiment provides a new type of hydraulic self-balancing parking device, which comprises a support shell 100, a sliding block assembly 200, a small-hole damper 300, a first one-way mechanism 400, a second one-way mechanism 500, a locking mechanism 600 and a soft rubber sealing gasket 800. The support shell 100 is the basic structure of the whole device and provides installation and support space for other parts of the device. The sliding block assembly 200 is slidably installed in the support shell 100 and divides the internal space into an upper cavity 101 and a lower cavity 102, and the two cavities are used for carrying hydraulic oil. The volume of the upper cavity 101 and the lower cavity 102 can be changed through the sliding of the sliding block assembly 200, so that the flow of the hydraulic oil is caused and a power source is provided for the actions of the device. The small-hole damper 300 is arranged in the sliding block assembly 200, and the upper cavity 101 and the lower cavity 102 are connected through the small hole of the small-hole damper 300. The sliding block assembly 200 is used in cooperation with the soft rubber sealing gasket 800 during the up-and-down movement.

[0063] The embodiment provides a new type of hydraulic self-balancing parking device, which comprises a support shell 100, a sliding block assembly 200, a small-hole damper 300, a first one-way mechanism 400, a second one-way mechanism 500, a locking mechanism 600 and a soft rubber sealing gasket 800. The support shell 100 is the basic structure of the whole device and provides installation and support space for other parts of the device. The sliding block assembly 200 is slidably installed in the support shell 100 and divides the internal space into an upper cavity 101 and a lower cavity 102, and the two cavities are used for carrying hydraulic oil. The volume of the upper cavity 101 and the lower cavity 102 can be changed through the sliding of the sliding block assembly 200, so that the flow of the hydraulic oil is caused and a power source is provided for the actions of the device. The small-hole damper 300 is arranged in the sliding block assembly 200, and the upper cavity 101 and the lower cavity 102 are connected through the small hole of the small-hole damper 300. The sliding block assembly 200 is used in cooperation with the soft rubber sealing gasket 800 during the up-and-down movement.

[0064] The uplink control spring cavity 401 is formed inside the slider assembly 200 and is in communication with the upper cavity 101. The first one-way mechanism 400 is arranged in the cavity. When the flow direction of the hydraulic oil meets the set conditions, the first one-way mechanism 400 allows the hydraulic oil to pass, so that the hydraulic oil can flow and act in the uplink control spring cavity 401 in a predetermined manner. When the hydraulic oil attempts to flow in the opposite direction, the first one-way mechanism 400 prevents the hydraulic oil from passing, ensuring that the flow direction of the hydraulic oil is strictly controlled, thereby achieving precise control of the device. The downlink control spring cavity 501 is also formed in the slider assembly 200 and is in communication with the lower cavity 102. The second one-way mechanism 500 is arranged, which has the same one-way conduction characteristics as the first one-way mechanism 400

[0065] The locking shaft passage 601 is located inside the slider assembly 200 and is in communication with the small hole of the small hole damper 300. The locking mechanism 600 is installed in the locking shaft passage 601. The locking mechanism 600 is locked or separated with the inner wall of the support shell 100. When the device is in different working states, the hydraulic oil flows in the related cavities and controls the action of the locking mechanism 600 through the corresponding control mechanism, so that it can be accurately locked or separated with the inner wall of the support shell 100, thereby realizing the switching of the device between the stop and continue running states. The annular passage 701 is arranged inside the slider assembly 200, which is in communication with the uplink control spring cavity 401, the downlink control spring cavity 501 and the locking shaft passage 601. The annular passage 701 builds an orderly hydraulic oil flow circulation path. Through the annular passage 701, the hydraulic oil can flow smoothly between different cavities, and cooperate with each component to complete the control of different actions. When the hydraulic oil is transferred between different cavities, the annular passage 701 plays a role of deployment, guidance and buffering, so that the work of the entire hydraulic system is more coordinated and stable, which helps to improve the overall performance of the device.

[0066] When the slider assembly 200 moves along the inside of the support shell 100, the volume of the upper cavity 101 and the lower cavity 102 changes, thereby causing the hydraulic oil to flow inside the device, and the locking mechanism 600 is separated or locked with the inner wall of the support shell 100.

[0067] For example, the support shell 100 includes a cylindrical shell 110, an upper end cover 120 and a lower end cover 130. The cylindrical shell 110, the upper end cover 120 and the lower end cover 130 are assembled together to form a closed cavity inside the support shell 100.

[0068] In some examples, the locking mechanism 600 includes two locking shafts 610, which are oppositely and slidably installed in the locking shaft channel 601; a locking spring 620, which is arranged between the two locking shafts 610 and is used to move the two locking shafts 610 away from each other; a locking head 630, which is arranged at one end of the locking shaft 610 away from the locking spring 620; and a rack 640, which is arranged on the inner wall of the support housing 100, and the locking head 630 is clamped with the rack 640 under the action of the locking spring 620. Meanwhile, the end of the locking head 630 away from the locking spring 620 is formed with two arc-shaped teeth, which are used to clamp with the rack 640.

[0069] For example, the pitch p2 of the two teeth of the locking head 630 is slightly larger than the pitch p1 of the positioning rack 640, which can avoid the phenomenon of being stuck when meshing, and the difference between the two pitches controls the positioning accuracy of the device, and the design positioning accuracy is less than 0.5 mm.

[0070] For example, the rack 640 corresponds to the locking head 630 in two, and the two racks 640 are oppositely embedded in the inner wall of the support object 100 and are used in cooperation with the locking head 630.

[0071] When the height of the load device is adjusted downward, the downward force applied to the support object generally reaches about 50% of the rated load, which acts together with the load to make the device lose balance and generate a downward driving force. This driving force is transmitted to the lower cavity 102 and the locking head 630 through the slider assembly 200, and the locking head 630 generates a small transverse displacement to make the slider assembly 200 have a downward movement trend. Due to the incompressible nature of the liquid, the liquid pressure in the lower cavity 102 is instantaneously increased, the soft rubber sealing pad 800 at the lower end surface of the small hole damper 300 is driven to adhere to the small hole surface of the small hole damper 300, sealing the small hole of the lower port of the small hole damper 300, and driving the downward control second one-way mechanism 500 to act, opening the channel of the downward control spring cavity 501, and the pressure is transmitted to the two outer ends of the locking shaft channel 601 through the annular channel 701, driving the locking shaft 610 and the locking head 630 to move to the center direction against the spring force of the locking spring 620, so that the locking head 630 is disengaged from the rack 640. At this time, the pressure in the upper cavity 101 is reduced, forming a negative pressure state, and the upper rubber plate of the soft rubber sealing pad 800 at the upper end surface of the small hole damper 300 is separated from the surface of the small hole damper 300, opening the upper port of the small hole damper 300, and the hydraulic medium flows to the upper cavity 101 through the channel and the gap. The slider assembly 200 drives the load device to adjust downward, and after adjustment, the applied external force is removed, only the load acts, and the pressure in the upper and lower cavities is balanced. At this time, the locking head 630 is engaged with the rack 640 again under the spring force of the locking spring 620, realizing the positioning of the new height position.

[0072] When the position is adjusted upwards, an upward force is applied to the load device. This force partially or completely offsets the downward force of the load. At this time, the load spring 720 acts on the bottom of the slider assembly 200 with a large driving force. This driving force is transmitted through the slider assembly 200 to the upper cavity 101 and the locking head 630. The locking head 630 generates a small lateral displacement, causing the slider assembly 200 to move upwards. Due to the incompressible nature of liquids, the liquid pressure in the upper cavity 101 can increase instantaneously, driving the soft rubber sealing gasket 800 on the upper end face of the orifice damper 300 to adhere to the upper surface of the orifice damper 300, sealing the upper port of the orifice damping channel 300. At the same time, it drives the first one-way mechanism to operate, opening the upward control spring cavity 401 channel. The pressure is released through the annular passage 701. The force is transmitted to the two outer ends of the locking shaft channel 601, driving the locking shaft 610 and locking head 630 to move towards the center against the spring force of the locking spring 620, causing the locking head 630 to disengage from the rack 640. At this time, the pressure in the lower chamber 102 decreases, forming a negative pressure state. The rubber plate of the soft rubber sealing gasket 800 on the lower end face of the small hole damper 300 disengages from the surface of the small hole damper 300, opening the lower port of the small hole damping channel 300. The hydraulic medium flows into the lower chamber 102 through the channel and gap, while the slider assembly 200 drives the load device to move upward for adjustment. After adjustment, the external force is applied and removed, and only the load is active. The pressure in the upper and lower chambers is balanced. At this time, the locking head 630 engages with the rack 640 again under the spring force of the locking spring 620, achieving the positioning of the new height position.

[0073] like Figures 1 to 9 As shown, in some examples, the first one-way mechanism 400 includes: an upward control spring 410 disposed within the upward control spring cavity 401; and a first locking ball 420 disposed within the upward control spring cavity 401 and connected to the upward control spring 410. The first locking ball 420, under the action of the upward control spring 410, blocks the port connecting the upward control spring cavity 401 and the upper cavity 101.

[0074] In the technical solution, the first one-way mechanism 400 comprises an uplink control spring 410 and a first locking ball 420. The uplink control spring 410 is arranged in the uplink control spring cavity 401 and connected with the first locking ball 420, and can provide a continuous force for the first locking ball 420. The first locking ball 420 is also arranged in the uplink control spring cavity 401. When hydraulic oil flows from the upper cavity 101 to the uplink control spring cavity 401, and a certain hydraulic condition is met, the force of the hydraulic oil on the first locking ball 420 can overcome the spring force of the uplink control spring 410, so that the first locking ball 420 deviates from the blocking position, opens the channel between the uplink control spring cavity 401 and the upper cavity 101, and allows the hydraulic oil to pass smoothly, thereby ensuring that the liquid flow can realize the conduction in a specific direction. However, in the case of reverse liquid flow, the spring force of the uplink control spring 410 tightly blocks the first locking ball 420 at the port connecting the uplink control spring cavity 401 and the upper cavity 101, effectively preventing the hydraulic oil from flowing in the reverse direction. The uplink control spring 410 and the first locking ball 420 cooperate with each other to realize the one-way conduction function of the first one-way mechanism 400.

[0075] As shown in Figures 1 to 9 In some examples, the second one-way mechanism 500 comprises a downlink control spring 510 arranged in a downlink control spring cavity 501, and a second locking ball 520 arranged in the downlink control spring cavity 501 and connected with the downlink control spring 510. The second locking ball 520 blocks the port connecting the downlink control spring cavity 501 and the lower cavity 102 under the action of the downlink control spring 510.

[0076] In the technical solution, the working principle of the second one-way mechanism 500 is similar to that of the first one-way mechanism 400. The downlink control spring 510 is arranged in the downlink control spring cavity 501 and connected with the second locking ball 520. When the device is in a normal operating state and no specific hydraulic action is triggered, the second locking ball 520 blocks the port connecting the downlink control spring cavity 501 and the lower cavity 102 under the action of the spring force of the downlink control spring 510, thereby ensuring the hydraulic isolation between the lower cavity 102 and the downlink control spring cavity 501 when the hydraulic oil does not need to flow, preventing the hydraulic oil from flowing in the reverse direction as desired, and maintaining the stability of the internal pressure and hydraulic state of each chamber.

[0077] The downlink control spring 510 and the second locking ball 520 cooperate to realize the one-way conduction function of the second one-way mechanism 500. When the downlink control requires the hydraulic oil to flow from the lower cavity 102 to the downlink control spring cavity 501, as long as the pressure of the hydraulic oil meets the positive condition set by the device, the external force of the hydraulic oil on the second locking ball 520 can overcome the spring force of the downlink control spring 510, and the second locking ball 520 will deviate from the blocking position to open the channel between the downlink control spring cavity 501 and the lower cavity 102.

[0078] The slider assembly 200 comprises a slider 210 slidingly installed in the support housing 100, and a main shaft 220 fixedly installed at the upper end of the slider 210 and slidingly penetrating the upper wall of the support housing 100.

[0079] As shown in some examples, a load adjusting mechanism 700 is arranged between the lower end surface of the slider assembly 200 and the inner wall of the support housing 100, for adjusting the load of the slider assembly 200. Figures 1 to 9 The load adjusting mechanism 700 comprises a load adjusting knob 710 rotatably installed at the lower end surface of the support housing 100, and a load spring 720 arranged between the load adjusting knob 710 and the lower end surface of the slider assembly 200.

[0080] In the technical scheme, the balance of the load is mainly provided by the spring force of the load spring 720, the bottom of the load spring 720 is installed on the load adjusting knob 710, the load adjusting knob 710 is screwedly installed in the middle of the lower end cover 130, and the load adjusting knob 710 can adjust the pre-tightening force of the load spring 720 through the threaded structure between the load spring 720 and the lower end cover 130 in addition to the supporting and positioning effect of the load spring 720, so that about 20% of the adjustment amount can be provided on the basis of the rated load value, and therefore the use of different load sizes can be adapted within a certain range of the rated load.
