Description

An engine mounting bracket for a pipe-laying machine Technical Field

[0001] This utility model belongs to the technical field of pipe-laying machine equipment, specifically, it relates to an engine suspension bracket for a pipe-laying machine. Background Technology

[0002] In modern industrial construction, pipe-laying machines are important engineering machinery used for pipeline laying and hoisting operations. Their performance and reliability directly affect the progress and quality of the project. As the power core of the pipe-laying machine, the stable operation and effective support of the engine are crucial, and the engine mounting bracket is the key component for achieving reliable engine installation and support.

[0003] Currently, most engine mounting brackets for pipe-laying machines on the market adopt the traditional rigid connection method, which mainly connects the bracket directly to the engine block with bolts. Although this connection method can ensure the installation stability of the engine to a certain extent, it requires repeated tightening of a large number of bolts during the installation and disassembly of the engine. The operation is cumbersome and time-consuming. Especially in some emergency repairs or equipment replacements, this inefficient disassembly and assembly method will seriously affect the project progress, increase equipment downtime and maintenance costs. Moreover, frequent tightening of bolts can easily lead to bolt wear and loosening, reduce the reliability of the connection, and increase safety hazards. In view of this, this utility model is proposed. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an engine suspension bracket for a pipe-laying machine that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: an engine suspension bracket for a pipe-laying machine, comprising two connecting plates, on which screws inserted into fixing lugs on both sides of the engine cylinder block are symmetrically fixedly connected; further comprising: a support frame plate installed on the pipe-laying machine, on which two limiting shells are symmetrically fixedly connected; a vertical plate, fixedly connected to the lower end of the connecting plates; a pressure plate, fixedly connected to the lower end of the vertical plate; and an air supply bladder, disposed inside the lower end of the limiting shells, wherein the air supply bladder enters and exits... One-way valves are installed at each air inlet; side shells are symmetrically fixedly connected to both sides of the limiting shell, and the side wall of the limiting shell has an opening communicating with the side shell; a limiting frame plate is slidably connected in the side shell; a tensioning airbag for pushing the limiting frame plate into the limiting shell is disposed in the side shell, and both sides of the tensioning airbag are fixedly connected to the side shell and the limiting frame plate respectively; the air outlet of the air supply airbag is connected to the air inlets of two adjacent tensioning airbags through a three-way pipe, and an exhaust valve pipe is connected to the air outlet of the tensioning airbag.

[0006] To facilitate the quick return of the limiting frame plate and avoid jamming, the side of the limiting frame plate away from the vertical plate extends outward through the side plate shell, and multiple telescopic springs are fixedly connected at equal intervals between the outer wall of the side plate shell and the limiting frame plate.

[0007] To facilitate smoother movement of the pressure plate, both the pressure plate and the limiting frame plate have smooth surfaces.

[0008] To further prevent damage to the smooth surfaces of the pressure plate and the limiting frame plate, the upper surface of the pressure plate and the side of the limiting frame plate near the vertical plate are provided with arc-shaped chamfers.

[0009] To further reduce the vibration force transmitted from the engine to the pipe-laying machine, a shock-absorbing rubber pad is fixedly connected between the connecting plate and the vertical plate.

[0010] To further enhance the strength and reduce the weight of the bracket, the support frame plate, connecting plate, vertical plate, pressure plate, limiting frame plate, limiting plate shell, and side plate shell are all made of high-strength, lightweight metal plates.

[0011] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention uses the combination of air supply airbag, tension airbag and limiting frame plate to fix and release the engine by compressing and releasing the gas, without having to repeatedly tighten the bolts, which greatly simplifies the engine installation and disassembly process, significantly improves the disassembly and assembly efficiency, and saves manpower and time costs.

[0012] In the installed state, the limiting frame plate is locked between the connecting plate and the pressure plate, structurally providing a reliable limit for the engine. Together with the connection between the screw and the engine cylinder block fixing lug, it ensures the stability of the connection between the engine and the suspension bracket from multiple directions. This allows the engine to be stably supported during the operation of the pipe-laying machine, reducing vibration transmission and component wear caused by loose connections, and improving the overall reliability of the pipe-laying machine.

[0013] The operation of this suspension bracket mainly revolves around the inflation and deflation of the airbag and simple hoisting operations. No complicated tools or professional skills are required. Workers only need to follow the established procedures to install and remove the engine by controlling the opening and closing of the exhaust valve pipe. The operation is simple and easy to understand, and it can flexibly cope with different working scenarios, meeting the needs of rapid engine installation and removal and stable operation in actual production.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] Example 1:

[0023] Referring to Figures 1-4, an engine mounting bracket for a pipe-laying machine includes two connecting plates 3, with screws 301 symmetrically fixedly connected to the connecting plates 3 and inserted into fixing lugs on both sides of the engine cylinder block. It also includes: a support frame plate 1 mounted on the pipe-laying machine, with two limiting shells 2 symmetrically fixedly connected to the support frame plate 1; a vertical plate 302 fixedly connected to the lower end of the connecting plates 3; a pressure plate 303 fixedly connected to the lower end of the vertical plate 302; an air supply bladder 4 disposed inside the lower end of the limiting shell 2, with one-way valves installed at both the inlet and outlet of the air supply bladder 4; and side shells 401 symmetrically... Fixedly connected to both sides of the limiting plate shell 2, the side wall of the limiting plate shell 2 has an opening that communicates with the side plate shell 401; the limiting frame plate 402 is slidably connected in the side plate shell 401; the tensioning airbag 403, which is used to push the limiting frame plate 402 into the limiting plate shell 2, is set in the side plate shell 401, and the two sides of the tensioning airbag 403 are fixedly connected to the side plate shell 401 and the limiting frame plate 402 respectively; the air outlet of the air supply airbag 4 is connected to the air inlet of the two adjacent tensioning airbags 403 through a three-way pipe 405, and the air outlet of the tensioning airbag 403 is connected to an exhaust valve pipe 406.

[0024] Before using the suspension bracket, first fix the connecting plate 3 on the fixing lug on the engine block with the screw 301 to complete the stable connection between the engine and the connecting plate 3. At the same time, fix the support frame plate 1 on the pipe-laying machine at the designated position for installing the engine with bolts to prepare for the subsequent installation of the engine.

[0025] Next, the engine is lifted by hoisting equipment, and the pressure plate 303 connected to the bottom of the connecting plate 3 via the vertical plate 302 slowly falls into the limiting plate shell 2. As the engine continues to fall, the pressure plate 303 compresses the air supply bag 4 under the action of the engine's gravity. Since the air supply bag 4 is equipped with one-way valves at both the inlet and outlet, the gas that is already filled inside when compressed can only enter the two adjacent tensioning bags 403 through the three-way pipe 405. When the pressure plate 303 has completely fallen into the limiting plate shell 2, the tensioning bag 403, due to the pressure of the gas it is filled with, pushes the limiting frame plate 402 into the limiting plate shell 2 and abuts against the vertical plate 302. At this time, the limiting frame plate 402 is stuck between the connecting plate 3 and the pressure plate 303, restricting the connecting plate 3 and the engine from the top and bottom, thereby completing the suspension support and fixation of the engine and realizing the connection between the engine and the pipe lifting machine.

[0026] When it is necessary to remove the engine from the pipe lifting machine, open the exhaust valve pipe 406 on the tension airbag 403, the gas in the tension airbag 403 is discharged, and it retracts itself, which drives the limit frame plate 402 to move back into the side plate shell 401, releasing the restriction on the pressure plate 303. At this time, the engine is no longer constrained by the limit frame plate 402, and the staff can easily lift the engine off the pipe lifting machine with the hoisting equipment.

[0027] Existing engine mounts mostly use bolts to directly connect to the engine block, requiring repeated tightening of bolts during installation and removal, which is cumbersome and time-consuming. This mount, however, uses a combination of air supply airbag 4, tension airbag 403, and limiting frame plate 402 to fix and release the engine by compressing and releasing gas, eliminating the need for repeated tightening of bolts. This greatly simplifies the engine installation and removal process, significantly improves installation and removal efficiency, and saves manpower and time costs.

[0028] In the installed state, the limiting frame plate 402 is locked between the connecting plate 3 and the pressure plate 303, which provides a reliable limit for the engine from a structural perspective. Together with the connection between the screw 301 and the engine cylinder block fixing lug, it ensures the stability of the connection between the engine and the suspension bracket from multiple directions. This allows the engine to be stably supported during the operation of the pipe-laying machine, reducing problems such as vibration transmission and component wear caused by loose connections, and improving the overall reliability of the pipe-laying machine.

[0029] The operation of this suspension bracket mainly revolves around the inflation and deflation of the airbag and simple hoisting operations. No complicated tools or professional skills are required. Workers only need to follow the established procedures to install and remove the engine by controlling the opening and closing of the exhaust valve pipe 406. The operation is simple and easy to understand, and it can flexibly cope with different working scenarios, meeting the needs of rapid engine installation and removal and stable operation in actual production.

[0030] Example 2:

[0031] Referring to Figures 1-4, an engine suspension bracket for a pipe-laying machine is basically the same as in Embodiment 1, but further: the side of the limiting frame plate 402 away from the vertical plate 302 extends outward through the side plate shell 401, and multiple telescopic springs 404 are fixedly connected at equal intervals between the outer wall of the side plate shell 401 and the limiting frame plate 402.

[0032] When the engine needs to be disassembled, and the exhaust valve pipe 406 is opened to allow the tensioned airbag 403 to retract, the telescopic spring 404 can assist the limiting frame plate 402 in moving back into the side plate shell 401. The elastic potential energy of the telescopic spring 404 itself can provide additional tension, accelerate the reset speed of the limiting frame plate 402, ensure that it can quickly and accurately return to the initial position, and release the restriction on the pressure plate 303 in time, making the engine disassembly process smoother and more efficient, and avoiding the problem of the limiting frame plate 402 getting stuck.

[0033] Example 3:

[0034] Referring to Figures 1-4, an engine mounting bracket for a pipe-laying machine is basically the same as in Embodiment 2, but with a further improvement: the surfaces of the pressure plate 303 and the limiting frame plate 402 are both smooth. When installing the engine, the pressure plate 303 falls into the limiting plate shell 2. The smooth surface reduces the frictional resistance between the pressure plate 303 and the limiting frame plate 402, allowing the pressure plate 303 to compress the air supply bag 4 more smoothly until it falls completely into the designated position, avoiding jamming due to surface roughness and improving installation efficiency. When disassembling the engine, the exhaust valve pipe 406 is opened, and the limiting frame plate 402 moves back. The smooth surface also reduces the resistance to separation between the two, making the engine lifting process easier and faster, further shortening the disassembly time.

[0035] The upper surface of the pressure plate 303 and the side of the limiting frame plate 402 near the vertical plate 302 are both provided with rounded chamfers. When installing the engine, the pressure plate 303 falls into the limiting plate shell 2, and the rounded chamfers on its upper surface can guide it, allowing the pressure plate 303 to fall into the designated position more accurately and smoothly, reducing the risk of collision or jamming with the edge of the limiting frame plate 402, and avoiding abnormal stress or damage to the air supply bag 4 due to installation obstruction. At the same time, the limiting frame plate 402 near the vertical plate 302 is also provided with rounded chamfers. The rounded chamfers on all four sides of the 02 side can also quickly fit with the pressure plate 303 when the tensioned airbag 403 pushes it into the limiting plate shell 2, reducing the time for adjusting the position of the components during installation and improving installation efficiency. During the contact and compression process between the pressure plate 303 and the limiting frame plate 402, the right-angled edges are easy to scratch each other's surfaces, accelerate component wear, and reduce service life. The rounded chamfers can reduce scratches and wear on the surface of the components and maintain the integrity of the surfaces of the pressure plate 303 and the limiting frame plate 402.

[0036] Example 4:

[0037] Referring to Figures 1-4, an engine suspension bracket for a pipe-laying machine is basically the same as in Embodiment 3, but with a further improvement: a shock-absorbing rubber pad 304 is fixedly connected between the connecting plate 3 and the vertical plate 302. During operation, the engine of the pipe-laying machine will generate continuous vibration, which is transmitted to the suspension bracket and the entire machine body through the connecting plate 3. The shock-absorbing rubber pad 304 has good elasticity and damping characteristics, which can effectively absorb and buffer the vibration energy of the engine, reduce the transmission of vibration to the vertical plate 302, the pressure plate 303 and the pipe-laying machine body. At the same time, it can suppress the noise generated by the vibration, reduce the impact of equipment operating noise on operators and the surrounding environment, and improve the comfort of the working environment and the quietness of equipment operation.

[0038] The support frame plate 1, connecting plate 3, vertical plate 302, pressure plate 303, limiting frame plate 402, limiting plate shell 2, and side plate shell 401 are all made of high-strength, lightweight metal plates. These high-strength metal plates can withstand the weight of the engine and various complex loads generated during operation, including vibration, torque, and impact. In the complex working environment of the pipe-laying machine, whether it's the bumps from rough roads or the forces generated by the engine operating under high load, these components can maintain a stable structural shape, avoiding deformation and breakage due to insufficient strength. This ensures the engine is securely installed and improves the reliability and safety of the entire suspension bracket system. The lightweight metal plates, while maintaining strength, significantly reduce the weight of the various components of the suspension bracket. For construction machinery like the pipe-laying machine that requires frequent movement and operation, reducing the weight of the suspension bracket helps reduce the overall vehicle weight, thereby reducing energy consumption and improving fuel economy. Furthermore, the reduced weight also reduces the vehicle's pressure on the ground, reduces tire wear, extends tire life, and lowers operating costs. Specifically, aluminum alloy materials can be used to make these components.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
