Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pump housings, in particular to a hydraulic pump protective housing. Background Art

[0002] A hydraulic pump is a device that converts mechanical energy into the pressure energy of hydraulic oil. It is the core power element of a hydraulic system. A hydraulic pump is usually composed of a motor and an oil pump. The motor drives the oil pump to rotate, sucking oil from the hydraulic oil tank, and then pressurizing the oil and discharging it to the actuator. Hydraulic pumps are widely used in various industries and mechanical equipment. A casing is generally installed on the hydraulic pump to protect the internal parts of the hydraulic pump from the external environment.

[0003] The hydraulic pump will accumulate heat after working for a period of time. Its shell only dissipates heat through the heat dissipation holes opened on the surface, which has a poor effect. In addition, the hydraulic pump will vibrate when working. The existing shell cannot simultaneously reduce vibration and dissipate heat.

[0004] In order to solve the above problems, a hydraulic pump protective housing is proposed in the present application. Utility Model Content

[0008] A base is provided at the bottom of the shell body, elastic parts are installed around the base, the shell body is installed on several elastic parts, a reciprocating air pusher connected to the shell body is installed on the base, and the reciprocating air pusher is connected to the heat dissipation chamber.

[0009] Preferably, the elastic member includes a fixed tube, the base is provided with mounting grooves on all four sides, a plurality of the fixed tubes are respectively installed in the corresponding mounting grooves, an insertion cavity is provided in the fixed tube, and a spring is installed in the insertion cavity, a telescopic rod inserted into the insertion cavity and connected to the spring is provided on the fixed tube, and the outer shell body is installed at the top ends of the plurality of telescopic rods.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] By setting the elastic parts and reciprocating air-pushing parts, the hydraulic pump can be installed in the installation chamber opened in the inner shell. When the hydraulic pump generates vibration during operation, it can be buffered by the elastic parts, and the elastic parts will then undergo elastic deformation. The outer shell body pushes the reciprocating air-pushing parts to move up and down, so that the gas can continuously enter the heat dissipation chamber formed between the outer shell body and the inner shell, and then be discharged through the heat dissipation holes opened on the periphery of the outer shell body, thereby increasing the air circulation speed in the heat dissipation chamber and improving the heat dissipation effect of the hydraulic pump in the inner shell. This structure can reduce the vibration of the hydraulic pump while dissipating heat, thereby improving the protection effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] like Figure 1-3 As shown, a hydraulic pump protective housing proposed by the utility model comprises a housing body 1 and an inner housing 2;

[0021] In this embodiment, the inner shell 2 is arranged in the outer shell body 1, an installation chamber is opened in the inner shell 2, a heat dissipation chamber is formed between the outer shell body 1 and the inner shell 2, and heat dissipation holes 3 are opened on the outer periphery of the outer shell body 1 and the inner shell 2 to penetrate and connect with the heat dissipation chamber.

[0022] In this embodiment, a base 4 is provided at the bottom of the housing body 1, elastic members 5 are installed around the base 4, and the housing body 1 is installed on a plurality of elastic members 5. The elastic member 5 includes a fixing tube 51, mounting grooves are provided around the base 4, and a plurality of fixing tubes 51 are installed in corresponding mounting grooves, respectively, an insertion cavity is provided in the fixing tube 51, and a spring 52 is installed in the insertion cavity, a telescopic rod 53 inserted into the insertion cavity and connected to the spring 52 is provided on the fixing tube 51, and the housing body 1 is installed on the top of the plurality of telescopic rods 53.

[0023] In this embodiment, a reciprocating air-pushing member 6 connected to the outer shell body 1 is installed on the base 4, and the reciprocating air-pushing member 6 is connected to the heat dissipation chamber. The reciprocating air-pushing member 6 includes an air cylinder 61, a through assembly channel is provided in the middle of the base 4, the air cylinder 61 is installed in the assembly channel, an air cavity is provided in the air cylinder 61, an air-pushing portion 62 connected to the outer shell body 1 is slidably provided in the air cavity, an air-guiding hose 63 connected to the air cavity is connected to the bottom of the air cylinder 61, and the end of the air-guiding hose 63 away from the air cylinder 61 is connected to the heat dissipation chamber. The air-pushing portion 62 includes a piston 621 and a connecting rod 622, the piston 621 is slidably provided in the air cavity, the connecting rod 622 is installed on the piston 621, and the end of the connecting rod 622 away from the piston 621 is connected to the bottom of the outer shell body 1.

[0024] It should be noted that in order to reduce the vibration of the hydraulic pump and dissipate heat at the same time, the hydraulic pump can be installed in the installation chamber opened in the inner shell 2. The heat generated by the hydraulic pump during operation can enter the heat dissipation chamber through the heat dissipation holes 3 opened on the outer periphery of the inner shell 2, and then dissipate through the heat dissipation holes 3 opened on the outer periphery of the outer shell body 1. When the hydraulic pump generates vibration during operation, the telescopic rod 53 moves downward in the fixed cylinder 51, which can be buffered by the spring 52. The spring 52 then undergoes elastic deformation, and the outer shell body 1 pushes the piston 621 connected to the connecting rod 622 to perform reciprocating up and down motions in the air cylinder 61. When the piston 621 moves upward, the external air enters the air cylinder 61 along the heat dissipation chamber and the air guide hose 63. When the piston 621 moves downward, the air in the air cylinder 61 enters the heat dissipation chamber along the air guide hose 63, and then is discharged through the heat dissipation holes 3 opened on the outer periphery of the outer shell body 1, thereby increasing the speed of air circulation in the heat dissipation chamber and improving the heat dissipation effect of the hydraulic pump in the inner shell 2. This structure can reduce the vibration of the hydraulic pump and dissipate heat at the same time, thereby improving the protection effect.

[0025] In a specific embodiment, damping support feet are installed around the bottom of the base 4.

[0026] It should be noted that the damping support feet provided can improve the vibration reduction effect of the hydraulic pump.
