Description

Technical Field

[0001] This invention relates to the field of pressure compensation technology, specifically to a low-energy hydraulic concrete demolition tool pressure compensation and adjustment device. Background Technology

[0002] Hydraulic concrete demolition tools are a type of engineering or emergency operation tool that is driven by hydraulic power and is specifically designed for breaking, demolishing, chiseling, and cutting concrete and reinforced concrete structures. The core relies on high-pressure hydraulic oil provided by the hydraulic power station to transmit power. It has the characteristics of large output force, high working efficiency, easy operation, and low vibration. It is widely used in building demolition, municipal renovation, fire emergency demolition, mining construction, road maintenance and other scenarios. It is a highly efficient demolition equipment that replaces traditional pneumatic picks, electric hammers and other equipment.

[0003] Hydraulic concrete demolition tools are core equipment in scenarios such as building demolition, road construction, and mining. Their operational efficiency and stability are highly dependent on the precise pressure control of the hydraulic system. As a key component of the hydraulic demolition system, the performance of the pressure compensation and adjustment device directly affects the operational effect, energy consumption level, and service life of the demolition tool.

[0004] Currently, the pressure compensation and adjustment devices of existing hydraulic concrete demolition tools still have shortcomings in practical applications, making it difficult to meet the needs of efficient, low-consumption, and convenient on-site operations. The core hydraulic components and fixed bases of existing devices are mostly integrated welded or bolted structures, requiring specialized tools for disassembly and assembly, which is cumbersome and time-consuming. When core components such as hydraulic presses and pressure compensators malfunction or require maintenance, the overall disassembly is difficult, significantly reducing the efficiency of on-site debugging and maintenance, and delaying the construction progress. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a low-energy-consumption hydraulic concrete demolition tool pressure compensation and adjustment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-energy hydraulic concrete demolition tool pressure compensation and adjustment device, comprising a fixed base, rotating wheels rotatably connected to the bottom of the front and rear sides of the fixed base, limit mechanisms provided on the left and right sides of the fixed base, a fixing mechanism provided inside the fixed base, a mounting frame provided on the top of the fixing mechanism, a hydraulic press fixedly connected to the top of the mounting frame, and a compensation mechanism provided on the top of the hydraulic press;

[0007] The fixing mechanism includes a worm gear rotatably connected to the inner side of the fixing base. An anti-slip disc is fixedly connected to the front of the worm gear. A worm wheel meshes with the left side of the worm gear. A rotating rod is fixedly connected inside the worm wheel. The rotating rod is rotatably connected to the inside of the fixing base. A linkage plate is fixedly connected to the top periphery of the rotating rod. An insert rod is fixedly connected to the outside of the linkage plate. A limit plate is fixedly connected to the top inner side of the fixing base. A limit rod is fixedly connected to the outside bottom of the mounting bracket. An insert plate is fixedly connected to the bottom of the mounting bracket.

[0008] Preferably, the mounting base has a groove inside that corresponds to the position of the insert plate, and the insert plate is inserted into the groove. The groove allows the insert plate to be inserted into the mounting base, limiting the mounting bracket and allowing the mounting bracket to be initially installed on the top of the mounting base.

[0009] Preferably, the insert plate has a corresponding insertion hole inside, and the insertion rod is inserted into the insertion hole. The insertion hole allows the insertion rod to be inserted into the insert plate, limiting the position of the insert plate and making it difficult for the insert plate to be pulled out from the fixed base, thus making the mounting bracket more stable after installation.

[0010] Preferably, the limiting plate is disposed on the back end of the linkage plate, and the front of the limiting plate is in contact with the back end of the linkage plate. The limiting plate can limit the position of the linkage plate. When the insert plate needs to be inserted into the fixed seat, the operator drives the worm gear to rotate through the anti-slip plate, so that the worm gear drives the rotating rod and the linkage plate to rotate towards the back end through the worm wheel, so that the linkage plate can contact the limiting plate, so that the linkage plate does not easily block the sliding groove opened inside the fixed seat, and the insert plate can be stably inserted into the fixed seat.

[0011] Preferably, the top of the fixed base has a sliding hole corresponding to the position of the limiting rod, and the limiting rod is inserted into the sliding hole. Through the sliding hole, the limiting rod can be inserted into the fixed base to limit the position of the mounting bracket.

[0012] Preferably, the limiting mechanism includes a fixed frame, which is fixedly connected to the left and right sides of the top of the fixed base. A threaded rod is rotatably connected inside the fixed frame. A rotating disk is fixedly connected to the top of the threaded rod. The bottom of the threaded rod is rotatably connected to the top of the fixed frame. A threaded plate is threadedly connected to the periphery of the threaded rod. A sliding rod is fixedly connected to the bottom of the threaded plate. A support disk is fixedly connected to the bottom of the sliding rod. Short rods are fixedly connected to the front and rear sides of the threaded plate.

[0013] Preferably, there are two slide rods, which are fixedly connected to the front and rear sides of the bottom of the threaded plate, and are slidably connected inside the fixed base. When the threaded plate moves up and down, the slide rods can drive the support plate to move downward, so that the support plate contacts the ground, making it difficult for the rotating wheel to rotate and making the device difficult to move by the rotating wheel.

[0014] Preferably, the fixed frame has a limiting groove inside that corresponds to the position of the short rod, and the short rod is slidably connected inside the limiting groove. Through the limiting groove, the short rod can slide inside the fixed frame to limit the threaded plate, making the threaded plate more stable during the lifting and lowering process.

[0015] Preferably, the compensation mechanism includes a connecting pipe, which is fixedly connected to the left side of the front of the hydraulic press. A compensator base is fixedly connected to the right side of the connecting pipe. A pressure compensator is installed on the top of the compensator base. A conveying pipe is fixedly connected to the right side of the compensator base, and a connector is fixedly connected to the right side of the conveying pipe.

[0016] Preferably, the compensator base and connector are fixedly connected to the top of the mounting frame. The compensator base can support the pressure compensator, and the connector facilitates the connection of hydraulic concrete demolition tool oil pipes.

[0017] Compared with the prior art, the present invention provides a low-energy hydraulic concrete demolition tool pressure compensation and adjustment device, which has the following beneficial effects:

[0018] 1. This low-energy hydraulic concrete demolition tool's pressure compensation and adjustment device uses a worm gear and worm wheel meshing transmission to drive the rotating rod and linkage plate to rotate, achieving rapid locking and unlocking of the insertion rod onto the insertion plate. During installation, the insertion plate and limit rod at the bottom of the mounting frame are inserted into the corresponding groove and sliding hole of the fixing seat to complete the initial limiting. Rotating the anti-slip plate will drive the insertion rod to insert into the insertion hole of the insertion plate, achieving a firm fixation of the mounting frame. The limit plate precisely limits the linkage plate, preventing it from obstructing the groove and affecting the insertion of the insertion plate, ensuring smooth disassembly and assembly. This enables rapid disassembly and assembly of core components such as hydraulic presses and pressure compensators, facilitating subsequent inspection, maintenance, and replacement of components, and significantly improving the efficiency of on-site operation debugging.

[0019] 2. The pressure compensation and adjustment device of this low-energy hydraulic concrete demolition tool has a limiting mechanism that drives the threaded rod to rotate through the rotating disc, drives the threaded plate to rise and fall stably along the fixed frame, and then drives the slide rod and support disc to move downward to contact the ground. The supporting force of the support disc restricts the rotation of the rotating wheel, so that the device will not be displaced due to the vibration of the hydraulic press or the impact of the demolition tool during operation, thus ensuring the overall operational stability of the device.

[0020] 3. The low-energy hydraulic concrete demolition tool pressure compensation and adjustment device has a compensation mechanism that is connected in sequence through a connecting pipe, compensator base, pressure compensator and delivery pipe, and connector. The hydraulic oil of the hydraulic press is precisely adjusted by the pressure compensator and then delivered to the hydraulic concrete demolition tool. The pressure compensator can dynamically compensate and adjust the hydraulic pressure according to the real-time load requirements of the demolition tool, so as to achieve precise matching of low pressure and small flow under light load and high pressure and large flow under heavy load. This avoids the overflow energy consumption caused by constant pressure oil supply in traditional hydraulic systems and greatly reduces the overall energy consumption of hydraulic operations.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] This invention provides the following technical solutions:

[0033] Example 1

[0034] Please see Figure 1-7 The present invention provides a technical solution: a low-energy hydraulic concrete demolition tool pressure compensation and adjustment device, including a fixed base 3, rotating wheels 1 rotatably connected to the bottom of the front and rear sides of the fixed base 3, limit mechanisms 7 provided on the left and right sides of the fixed base 3, a fixed mechanism 2 provided inside the fixed base 3, an installation frame 4 provided on the top of the fixed mechanism 2, a hydraulic press 6 fixedly connected to the top of the installation frame 4, and a compensation mechanism 5 provided on the top of the hydraulic press 6.

[0035] The fixing mechanism 2 includes a worm gear 23, which is rotatably connected to the inside of the fixing base 3. An anti-slip disc 24 is fixedly connected to the front of the worm gear 23. A worm wheel 22 is engaged on the left side of the worm gear 23. A rotating rod 21 is fixedly connected inside the worm wheel 22. The rotating rod 21 is rotatably connected to the inside of the fixing base 3. A linkage plate 25 is fixedly connected to the top of the outer periphery of the rotating rod 21. An insert rod 29 is fixedly connected to the outer side of the linkage plate 25. A limit plate 26 is fixedly connected to the top of the inside of the fixing base 3. A limit rod 27 is fixedly connected to the outer side of the bottom of the mounting bracket 4. An insert plate 28 is fixedly connected to the bottom of the mounting bracket 4.

[0036] Furthermore, the mounting base 3 has a groove inside that corresponds to the position of the insert plate 28, and the insert plate 28 is inserted into the groove. Through the groove, the insert plate 28 can be inserted into the mounting base 3 to limit the mounting bracket 4, so that the mounting bracket 4 can be initially installed on the top of the mounting base 3.

[0037] Furthermore, the insert plate 28 has an insertion hole corresponding to the position of the insertion rod 29, and the insertion rod 29 is inserted into the insertion hole. Through the insertion hole, the insertion rod 29 can be inserted into the insert plate 28, limiting the position of the insert plate 28 and making it difficult for the insert plate 28 to be pulled out from the fixed base 3, so that the mounting bracket 4 is more stable after installation.

[0038] Furthermore, the limiting plate 26 is set at the back end of the linkage plate 25, and the front of the limiting plate 26 is in contact with the back end of the linkage plate 25. The limiting plate 26 can limit the position of the linkage plate 25. When the insert plate 28 needs to be inserted into the fixed base 3, the operator drives the worm gear 23 to rotate through the anti-slip plate 24. The worm gear 23 drives the rotating rod 21 and the linkage plate 25 to rotate towards the back end through the worm wheel 22, so that the linkage plate 25 can contact the limiting plate 26. This prevents the linkage plate 25 from obstructing the sliding groove opened inside the fixed base 3, and allows the insert plate 28 to be stably inserted into the fixed base 3.

[0039] Furthermore, the top of the fixed base 3 is provided with a sliding hole corresponding to the position of the limiting rod 27, and the limiting rod 27 is inserted into the sliding hole. Through the sliding hole, the limiting rod 27 can be inserted into the fixed base 3 to limit the position of the mounting bracket 4.

[0040] Example 2

[0041] Please see Figure 1-7 Furthermore, based on Embodiment 1, the limiting mechanism 7 further includes a fixed frame 72, which is fixedly connected to the top left and right sides of the fixed base 3. A threaded rod 75 is rotatably connected inside the fixed frame 72. A rotating disk 71 is fixedly connected to the top of the threaded rod 75. The bottom of the threaded rod 75 is rotatably connected to the top of the fixed frame 72. A threaded plate 76 is threadedly connected to the outer periphery of the threaded rod 75. A sliding rod 73 is fixedly connected to the bottom of the threaded plate 76. A support disk 74 is fixedly connected to the bottom of the sliding rod 73. Short rods 77 are fixedly connected to the front and rear sides of the threaded plate 76.

[0042] Furthermore, there are two slide rods 73. The two slide rods 73 are fixedly connected to the front and rear sides of the bottom of the threaded plate 76, and the two slide rods 73 are slidably connected inside the fixed base 3. When the threaded plate 76 moves up and down, the slide rods 73 can drive the support plate 74 to move downward, so that the support plate 74 contacts the ground, making it difficult for the rotating wheel 1 to rotate, and making it difficult for the device to move by the rotating wheel 1.

[0043] Furthermore, the fixed frame 72 has a limiting groove inside that corresponds to the position of the short rod 77, and the short rod 77 is slidably connected inside the limiting groove. Through the limiting groove, the short rod 77 can slide inside the fixed frame 72 to limit the threaded plate 76, making the threaded plate 76 more stable during the lifting and lowering process.

[0044] Example 3

[0045] Please see Figure 1-7 Furthermore, based on Embodiment 1, the compensation mechanism 5 includes a connecting pipe 51, which is fixedly connected to the left side of the front of the hydraulic press 6. A compensator base 52 is fixedly connected to the right side of the connecting pipe 51. A pressure compensator 53 is installed on the top of the compensator base 52. A conveying pipe 54 is fixedly connected to the right side of the compensator base 52. A connector 55 is fixedly connected to the right side of the conveying pipe 54.

[0046] Furthermore, the compensator base 52 and connector 55 are fixedly connected to the top of the mounting bracket 4. The compensator base 52 can support the pressure compensator 53, and the connector 55 facilitates the connection of the hydraulic concrete demolition tool oil pipe.

[0047] In actual operation, when this device is used, it can be used in conjunction with the hydraulic press 6, connecting pipe 51 and pressure compensator 53 to adjust the pressure of the hydraulic concrete demolition tool. The pressure compensator 53 can dynamically compensate and adjust the hydraulic pressure according to the real-time load requirements of the demolition tool to achieve precise matching of light load, low pressure and small flow, and heavy load, high pressure and large flow.

[0048] When it is necessary to move the hydraulic press 6 and the pressure compensator 53, the mounting bracket 4, on which the hydraulic press 6 and the pressure compensator 53 are installed, is placed on top of the fixed base 3, so that the limiting rod 27 and the insert rod 29 at the bottom of the mounting bracket 4 can be inserted into the fixed base 3. The operator rotates the anti-slip plate 24, which drives the worm gear 23 to rotate, which drives the worm wheel 22 to rotate, which drives the linkage plate 25 to rotate through the rotating rod 21, so that the linkage plate 25 can drive the insert rod 29 to be inserted into the insert plate 28, limiting the insert plate 28, so that the mounting bracket 4 can be stably installed on top of the fixed base 3. The rotating wheel 1 makes it easy for the operator to move the hydraulic press 6 and the pressure compensator 53 to a suitable position.

[0049] When it is necessary to limit the rotation wheel 1, the operator rotates the rotating disk 71, which drives the threaded rod 75 to rotate. The threaded rod 75 drives the threaded plate 76 and the slide rod 73 to move downward, so that the slide rod 73 can drive the support disk 74 to contact the ground. This increases the friction between the bottom of the device and the ground, making the device less likely to move by the rotating wheel 1. This makes the device more stable when the hydraulic press 6 and the pressure compensator 53 are in use.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
