Description

Technical Field

[0001] The invention belongs to the field of excavator oil tank protection, and in particular relates to an excavator oil tank fixed protection structure. Background Art

[0002] Excavator, also known as excavation machinery, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and loads them into transport vehicles or unloads them to stockpiles. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rocks. From the development of engineering machinery in recent years, the development of excavators has been relatively fast, and excavators have become one of the most important engineering machinery in engineering construction. The three most important parameters of excavators are operating weight (mass), engine power and bucket capacity. Due to the harsh working environment of excavators and in actual use, in order to have a longer endurance, they need to be equipped with a large-capacity fuel tank as a power source.

The utility model sets a movable plate, a clamping block, a clamping groove and a telescopic spring, so that the telescopic spring resets and stretches to drive the movable plate to move, and the movable plate drives the clamping block to movably clamp with the inside of the clamping groove, so that it is convenient for the movable plate to fix and install the oil tank, and the operation is convenient and quick. It also sets a connecting rod, a threaded hole, a screw and a threaded groove, so that the screw is connected with the threaded hole and the threaded groove by thread, and the connecting rod is fixed and limited, thereby effectively ensuring that the clamping block fixes the oil tank firmly, and it is safer to use.

[0004] However, referring to the above background and prior art, it is known that when the existing excavator fuel tank is in use, since it is protected by directly welding corresponding guardrails on the outside of the fuel tank, the protection method using guardrails will still cause the fuel tank to deform or even leak oil when it is impacted, which will cause pollution to the surrounding environment and cause explosions.

[0005] Therefore, in view of the deficiencies in the actual production and implementation of the above-mentioned scheme, it is revised and improved. At the same time, in the spirit and concept of seeking for excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present invention is created. A fixed protection structure for an excavator oil tank is provided to solve the existing problem that when protecting, the corresponding guardrail is directly welded on the outside of the oil tank for protection. However, the protection method using the guardrail will still cause the oil tank to deform or even leak oil when it is impacted, which will cause pollution to the surrounding environment and cause explosions. Summary of the invention

[0006] The present invention proposes a fixed protection structure for an excavator oil tank, which solves the problem in the prior art that when performing protection, corresponding guardrails are mostly directly welded on the outside of the oil tank for protection. However, the protection method using guardrails still causes the oil tank to deform or even leak oil when it is impacted, which in turn causes pollution to the surrounding environment and causes explosions.

[0007] The technical solution of the present invention is achieved as follows: a fixed protective structure for an excavator oil tank includes a support plate, a through hole for installing an air supply pipe is opened inside the support plate, a supply pipe is fixedly connected to one side of the air supply pipe, a one-way valve is installed on the outside of the supply pipe, and a cylindrical support rod is installed on the side of the air supply pipe away from the supply pipe, a baffle with a circular cross-section is fixedly connected to the outside of the support rod, the support rod is limited in the air supply pipe by the baffle fixedly connected on its outer surface, and an L-shaped connecting frame is fixedly connected to the side of the support rod away from the baffle, and a rectangular guard plate is fixedly connected to the top surface of the longitudinal member in the connecting frame, a heat dissipation groove is opened inside the guard plate, and dampers are fixedly connected to the four inner corners of each guard plate, and the side of the damper away from the guard plate is connected to the outer wall of the base.

[0008] As a preferred embodiment, a rectangular mounting plate is fixedly connected to the top surface of the base, and guide rails are fixedly connected to the four sides of the base in a circular array.

[0012] As a preferred embodiment, a cylindrical lifting rod is installed inside the lifting tube, and a blocking plate is fixedly connected to the bottom end of the lifting rod. The lifting rod is limited in the lifting tube by the blocking plate fixedly connected on its outer surface.

[0013] As a preferred embodiment, the support plates are provided at four locations, and the four support plates are respectively fixedly connected to the four corners of the bottom end surface of the base.

[0017] After using the above technical solution, the beneficial effects of the present invention are:

[0018] 1. In the present invention, by providing a damper fixedly connected to the base and the inner side of the guard plate, when the oil tank is installed on the pallet, the damper can be used to perform a force relief protection operation for the impact force currently exerted on the guard plate. After the force relief protection is completed, the oil tank placed on the pallet can be prevented from being damaged by excessive impact. Compared with the traditional guardrail protection structure, this design can significantly prevent the guardrail from being inserted into the interior of the oil tank when it is impacted, causing damage to the oil tank and oil leakage.

Compared with the traditional fixed design, the oil tank can perform active evasive protection operation when the oil tank is impacted, thereby achieving a more practical purpose. Compared with the traditional protection structure that can only protect by reinforcing the oil tank, this design can reduce the damage to the oil tank when it is hit without significantly increasing the overall weight of the device.

[0020] 3. In the present invention, by providing a heat dissipation groove in the guard plate, when the fuel tank is being reinforced and fixed, the setting of the heat dissipation groove can not only reduce the overall weight of the guard plate, but also can timely discharge the residual heat generated by the fuel tank and its auxiliary components during operation by utilizing the setting of the heat dissipation groove, so that when the excavator is moving, the active wind collision structure can be used to promote the circulation of wind around the fuel tank, so that when it is in use, the safety hazard of explosion of the fuel tank caused by high temperature can be avoided.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 9As shown, a fixed protection structure for an excavator oil tank includes: a support plate 18, a through hole for installing an air supply pipe 19 is opened inside the support plate 18, a supply pipe 20 is fixedly connected to one side of the air supply pipe 19, a one-way valve 21 is installed on the outer side of the supply pipe 20, and a cylindrical support rod 22 is installed on the side of the air supply pipe 19 away from the supply pipe 20, a baffle 23 with a circular cross-section is fixedly connected to the outer side of the support rod 22, the support rod 22 is limited in the air supply pipe 19 by the baffle 23 fixedly connected on its outer side surface, and an L-shaped connecting frame 24 is fixedly connected to the side of the support rod 22 away from the baffle 23, and a rectangular guard plate 25 is fixedly connected to the top surface of the longitudinal member in the connecting frame 24, and a heat dissipation groove 26 is opened inside the guard plate 25, each The four inner corners of the guard plate 25 are fixedly connected with dampers 27, and the side of the damper 27 away from the guard plate 25 is connected to the outer wall of the base 1. The oil tank 16 is placed on the inner side of the support 9 fixedly connected to the inner side of the moving seat 7, and the fixing bolt 11 is passed through the positioning hole 10 opened in the support 9 to achieve the quick fixing operation of the oil tank 16. After the fixing and limiting of the oil tank 16 is completed, the oil tank 16 is placed on the tray 15 fixedly connected to the top end surface of the lifting rod 13. At this time, the base 1 is connected to the excavator body by using the mounting plate 2 fixedly connected on its top end surface, and the bolt is passed through the mounting hole 3 opened in the mounting plate 2 to connect and position it with the excavator body.

[0034] Among them, a rectangular mounting plate 2 is fixedly connected to the top surface of the base 1, and guide rails 4 are fixedly connected to the four sides of the base 1 in a circular array. A longitudinal guide groove 5 is opened inside the guide rail 4, and a cylindrical guide rod 6 is fixedly connected to the outer side of the guide rail 4. A moving seat 7 is installed inside the guide groove 5, and two sliders 8 are fixedly connected to the outer side of each moving seat 7. The guide rod 6 plays the purpose of anti-collision and buffering protection of the oil tank. By fixing the slider 8 with a raised structure on the outer side of the moving seat 7, the moving seat 7 can be smoother when moving, and can be prevented from slipping out by the limiting position of the slider 8.

[0035] Among them, a longitudinal support member 9 is fixedly connected to the side of the movable seat 7 away from the guide rail 4, and a positioning hole 10 for installing a fixing bolt 11 is opened inside the support member 9, a lifting tube 12 is fixedly connected to the inner bottom end surface of the base 1, and a through hole for connecting with the supply pipe 20 is opened on the outer peripheral surface of the lifting tube 12, and a cylindrical lifting rod 13 is installed inside the lifting tube 12, and a baffle 14 is fixedly connected to the bottom end of the lifting rod 13. The lifting rod 13 is limited in the lifting tube 12 by the baffle 14 fixedly connected on its outer surface. When in use, the high-temperature gas generated by the operation of components such as the oil tank 16 can be quickly discharged.

[0036] Among them, a tray 15 is fixedly connected to the top surface of the lifting rod 13, and an oil tank 16 is placed above the tray 15. A filling pipe 17 that is connected to the top surface of the oil tank 16 is fixedly connected. By providing the filling pipe 17 that is connected to the oil tank 16, the oil can be filtered by adding a corresponding filter inside the filling pipe 17.

[0037] Among them, there are four support plates 18, and the four support plates 18 are respectively fixedly connected to the four corners of the bottom end surface of the base 1, the support plate 18 and the bottom end surface of the base 1 are vertically arranged, and the four corners of the mounting plate 2 are provided with mounting holes 3. When the guard plate 25 is impacted and the damper 27 is squeezed and buffered, the connecting frame 24 fixedly connected to the bottom end surface can be synchronously driven to move toward one side of the air supply pipe 19, and the support rod 22 and the baffle 23 are driven by the fixed connection to the connecting frame 24 to penetrate into the inside of the air supply pipe 19 to release the gas in the air supply pipe 19. After being quickly compressed, the gas is supplied to the inner position of the supply pipe 20 fixedly connected to the rear side of the supply pipe 19. At this time, the one-way valve 21 arranged on the outer side of the supply pipe 19 is opened, so that the gas in the supply pipe 19 can be supplied to the inner position of the lifting pipe 12 arranged in the base 1. This design can realize the linkage protection operation through the active supply of gas, and can reduce the maintenance cost compared with the complex mechanical structure. When the tray 15 moves upward, the oil tank 16 and its accessories can be synchronously moved upward to avoid the impact force of the collision, thereby achieving the purpose of efficient protection.

[0038] When in use, when the excavator oil tank 16 is being fixedly installed, the oil tank 16 can be placed on the inner side of the support member 9 fixedly connected to the inner side of the moving seat 7, and the fixing bolt 11 can be passed through the positioning hole 10 opened in the support member 9 to achieve a quick fixing operation of the oil tank 16. After the fixing and limiting of the oil tank 16 is completed, the oil tank 16 can be placed on the tray 15 fixedly connected to the top end surface of the lifting rod 13. When the oil tank 16 is installed, it is necessary to make the installation position of the oil tank 16 centered. At this time, the base 1 is connected to the pre-opened hole in the excavator body by using the mounting plate 2 fixedly connected on its top end surface, and the bolt is passed through the mounting hole 3 opened in the mounting plate 2 to connect and position with the excavator body.

[0039] After the assembly is completed, the oil filling operation can be performed by using the filling pipe 17 fixedly connected to the top surface of the oil tank 16, and after the filling is completed, the excavator can be supplied with oil for use as a driving source, and when in use, if the guard plate 25 arranged on the outside of the damper 27 is impacted, it can realize automatic and efficient buffering protection operation through contact with the damper 27 arranged on the outside of the base 1, and the inside of the guard plate 25 is also provided with heat dissipation grooves 26 in a linear array, so that when it is used, the high-temperature gas generated by the oil tank 16 and other components when working can be quickly discharged;

[0040] When the guard plate 25 is in use, when it is impacted and the damper 27 is squeezed and buffered, the connecting frame 24 fixedly connected to the bottom end surface thereof can be synchronously driven to move toward one side of the air supply pipe 19, and the supporting rod 22 and the baffle plate 23 fixedly connected to the connecting frame 24 are driven to penetrate into the interior of the air supply pipe 19, so that the gas in the air supply pipe 19 is quickly compressed and supplied to the internal position of the supply pipe 20 fixedly connected to the rear side of the air supply pipe 19. At this time, the one-way valve 21 arranged on the outside of the air supply pipe 19 is opened, so that the gas in the air supply pipe 19 can be supplied to the inner position of the lifting pipe 12 arranged in the base 1;

[0041] When the gas enters the lifting tube 12, the lifting rod 13, the baffle plate 14 and the tray 15 can be moved upward synchronously. When the tray 15 moves upward, the oil tank 16 and its accessories can be moved upward synchronously to avoid the impact force of the collision, thereby achieving the purpose of efficient protection. Compared with the traditional protection structure that can only protect by reinforcing the oil tank, this design can reduce the damage to the oil tank when it is hit without significantly increasing the overall weight of the device.
