DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Reference Figure 1-3 , a new type of hydraulic motor, comprising:

[0026] A mounting base 1, wherein a hydraulic motor 11 is disposed inside the mounting base 1, and vents 12 are provided on the upper wall and the lower wall of the mounting base 1;

[0027] The fixing assembly 2 includes a slide groove 21, a wedge plate 22, a concave fixing plate 23 and a spring 24. The upper wall and the lower wall of the mounting seat 1 are both provided with a slide groove 21. A wedge plate 22 is slidably connected in each slide groove 21. The upper and lower outer walls of the mounting seat 1 are both fixedly connected with a concave fixing plate 23. The two wedge plates 22 are elastically connected to the inner walls of the two concave fixing plates 23 through two springs 24 respectively.

[0028] It should be noted that when installing the hydraulic motor 11, it is only necessary to press the hydraulic motor 11 into the mounting seat 1 to squeeze the two wedge plates 22 into the two concave fixing plates 23 respectively. After the hydraulic motor 11 completely enters the mounting seat 1, the two wedge plates 22 automatically pop out and abut against the hydraulic motor 11 under the elastic force of the spring 24, and automatically fix the hydraulic motor 11. The operation is convenient. The two wedge plates 22 are provided with pull ropes 221 on the side away from the hydraulic motor 11. The two pull ropes 221 respectively pass through the two concave fixing plates 23 and are fixedly connected with pull rings 222. When disassembling the hydraulic motor 11, it is only necessary to pull the two pull rings 222 to pull out the two wedge plates 22 through the two pull ropes 221, so that the wedge plates 22 no longer abut against the hydraulic motor 11.

[0029] The cooling assembly 3 includes a heat transfer plate 31, a side cavity 32, an air bag 33, a push plate 34, two conductive sheets 35 and two cooling plates 36. The side wall of the mounting seat 1 is provided with a heat transfer plate 31, the side wall of the mounting seat 1 is provided with a side cavity 32, the side cavity 32 is provided with an air bag 33, and the heat transfer plate 31 extends into the side cavity 32 and is located below the air bag 33. The side cavity 32 is slidably connected with a push plate 34, and the push plate 34 is located above the air bag 33. The upper wall of the side cavity 32 and the top of the push plate 34 are provided with conductive sheets 35, and cooling plates 36 are provided in the two vents 12.

[0030] It is worth mentioning that when the two conductive sheets 35 are in contact, the two cooling plates 36 start to work. Mercury is contained in the airbag 33, which expands when heated. When the hydraulic motor 11 is overheated, the heat is transferred to the airbag 33 through the heat transfer plate 31, thereby expanding the airbag 33 and pushing the push plate 34 to move upward, so that the two conductive sheets 35 are in contact, and then the two cooling plates 36 are opened. The air above the hydraulic motor 11 expands when heated and rises upward. After encountering the cooling plate 36 above, the hot air contracts when cooled and sinks downward, and passes through the surrounding side of the hydraulic motor 11 from The air is discharged from the lower vent 12, and the air below the hydraulic motor 11 sinks directly after encountering the cooling plate 36 below, and is discharged from the lower vent 12, so that air circulation and cooling treatment can be performed on the surrounding side of the hydraulic motor 11, avoiding overheating of the hydraulic motor 11 and causing damage to its internal parts, thereby improving the service life of the hydraulic motor 11. The upper vent 12 of the two vents 12 has a dustproof net 121 on its top, so as to prevent dust from falling from the upper vent 12 to the upper wall of the hydraulic motor 11 and affecting the heat dissipation effect of the hydraulic motor.

[0031] The functional principle of the utility model can be explained through the following operation modes:

[0032] When in use, the hydraulic motor 11 is pressed into the mounting seat 1. After the hydraulic motor 11 is completely in the mounting seat 1, the two wedge plates 22 automatically pop out to fix the hydraulic motor 11, which is convenient for installation. When the hydraulic motor 11 is overheated, the air temperature around it increases, and then the heat is transferred to the air bag 33 through the heat transfer plate 31, so that the air bag 33 expands, and the two conductive sheets 35 are in contact, and then the two cooling plates 36 are opened to circulate and cool the air around the hydraulic motor 11, thereby avoiding the hydraulic motor 11 from overheating and reducing its service life. When it needs to be disassembled after use, pull the two pull rings 222 so that the two pull ropes 221 pull the two wedge plates 22 into the two concave fixing plates 23 respectively, and the two wedge plates 22 no longer abut the hydraulic motor 11, and the hydraulic motor 11 can be taken out. The operation is convenient and practical.

[0033] The above description is only a preferred specific implementation method of the utility model, but the protection scope of the new model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical scheme and utility model concept of the utility model, shall be covered by the protection scope of the utility model.
