Description

Technical Field

[0001] The utility model relates to the technical field of gear pump applications, and particularly relates to a gear pump and motor assembly testing machine that is convenient to carry. Background Technique

[0002] A gear pump and motor assembly is a mechanical device that combines a gear pump and a motor and is commonly used in hydraulic systems. The gear pump transports liquid through the rotation of two gears and has the advantages of simple structure, strong durability, and good self-priming ability. The motor provides power for the gear pump, enabling it to work stably and efficiently.

[0003] The Chinese patent discloses a gear pump and motor assembly testing machine (publication number: CN218062621U). By setting support columns, telescopic square columns, motor B, lead screws, motor C, and winding wheels, the effect of conveniently hoisting and loading / unloading the gear pump is achieved. The gear pump assembly is lifted by motor C and a rope, and then moved to the top of the test bench by motor B and lead screws to solve the problem that most gear pump assembly test mechanisms require manual handling of the gear pump assembly for loading and unloading. The gear pump assembly is heavy, resulting in a large labor intensity for test personnel, and it is extremely easy to cause collisions to the test mechanism during the handling and movement process, which is extremely likely to cause damage to the test mechanism.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0029] As Figures 1-5 shown, a gear pump and motor assembly testing machine convenient for handling includes a lifting mechanism 1, and a support mechanism 2 is arranged above the lifting mechanism 1. The lifting mechanism 1 includes control equipment 104 and an experimental component 105; further includes: the support mechanism 2 includes a support plate 201. Hanging ears 202 are symmetrically and fixedly connected to the front and back of the support plate 201. A plurality of installation grooves 203 are formed in the top surface of the hanging ears 202, and the length direction of each installation groove 203 is the same as the length direction of the support plate 201. A limiting plate 205 is fixedly connected to one side of the top surface of the support plate 201, and the top of the limiting plate 205 extends vertically upward; among them, a plurality of support wheels 204 are rotatably connected to the inside of each installation groove 203. The top ends of the support wheels 204 are located above the top surface of the support plate 201, and the installation grooves 203 are arranged at equal intervals along the length direction of the support wheels 204; among them, a buffer block 206 is slidably connected to the side of the limiting plate 205 close to the support plate 201. The length direction of the buffer block 206 is the same as the width direction of the support plate 201. As Figure 4 shown, a rubber layer is wrapped around the outside of the buffer block 206, so as to prevent the gear pump assembly from hitting the equipment shell 103 due to inertia when it is pushed to move above the support plate 201.

[0030] The middle of the inner wall of the support plate 201 is provided with a slot 213. On both sides of the slot 213 on the inner wall of the support plate 201, anti-slots 207 are symmetrically provided. The inner wall of the anti-slots 207 is slidably connected with extrusion blocks 212. The side of the extrusion block 212 close to the slot 213 is set as an inclined surface. On the side of the extrusion block 212 far from the slot 213, a guide rod 208 is fixedly connected. The other end of the guide rod 208 extends to the outside of the support plate 201, and the surface of the guide rod 208 is slidably connected with the inner wall of the support plate 201. One end of the guide rod 208 outside the support plate 201 is fixedly installed with a movable plate 209. In the middle of the inner wall of the movable plate 209, a lead screw 210 is threadedly connected. One end of the lead screw 210 is rotatably connected with the surface of the support plate 201. The other end of the lead screw 210 passes through the movable plate 209 and is fixedly installed with a knob 211, as Figure 5 shown, the guide rod 208 can only move linearly on the inner wall of the support plate 201, so that the moving direction of the movable plate 209 is limited by the guide rod 208;

[0031] The lifting mechanism 1 includes a base 101. On one side of the top surface of the base 101, an equipment housing 103 is fixedly installed. On the other side of the top surface of the base 101, a support frame 107 is fixedly installed. In the middle of the top surface of the base 101, a placement groove 102 is provided. The inner side of the placement groove 102 is movably connected with the support plate 201. The lower end of the inner wall of the equipment housing 103 is fixedly installed with a control device 104. The upper end of the inner wall of the equipment housing 103 is fixedly installed with an experimental component 105. The control device 104 is electrically connected to the experimental component 105. In the middle of the inner wall of the equipment housing 103, a hydraulic cylinder 106 is fixedly installed. The extending end of the hydraulic cylinder 106 is fixedly connected with a connecting head 114. On both sides of the outer wall of the connecting head 114, anti-blocks 115 are slidably connected. The outer sides of the two anti-blocks 115 are inclined surfaces. On one side of the two anti-blocks 115 inside the connecting head 114, a spring 116 is fixedly connected. The other end of the spring 116 is fixedly connected with the inner wall of the connecting head 114, as Figure 3 shown, the spring 116 pushes the anti-block 115 to extend out of the outside of the connecting head 114;

[0032] At the top of the support frame 107, an installation frame 108 is fixedly installed. The side of the installation frame 108 is fixedly connected with the upper surface of the base 101. At the lower end of the side wall of the installation frame 108, motors 109 are symmetrically fixedly installed. The output shaft of each motor 109 penetrates into the installation frame 108 and is fixedly connected with a winding roller 110. The side of the winding roller 110 is rotatably connected with the inside of the installation frame 108. On both sides of the outer wall of the winding roller 110, suspension ropes 112 are bound and connected. The suspension ropes 112 extend downward out of the installation frame 108. At the bottom surface of the installation frame 108 and on both sides of the suspension ropes 112, limiting wheels 111 are rotatably connected. The side of the limiting wheel 111 abuts against the suspension rope 112. The bottom end of the suspension rope 112 is fixedly connected with a hook 113. The inside of the hook 113 is movably connected with a hanging ear 202, as Figure 2, Figure 4 As shown, each hanging ear 202 fixes the lifting rope 112 through the hanging hook 113, thereby ensuring the stability when the support 201 is lifted or lowered.

[0033] The inner wall of the slot 213 is inserted into the connector 114, and the inner wall of the abutting slot 207 is inserted into the abutting block 115. One side of the inclined surface of the abutting block 115 abuts against one side of the inclined surface of the extrusion block 212. As Figure 5 shown, when the extrusion block 212 moves to the left, the extrusion block 212 pushes the abutting block 115 to contract into the inside of the connector 114.

[0034] The working principle of the present utility model:

[0035] When detecting the gear pump assembly, first push the gear pump assembly from above the base 101 to above the support plate 201. Then start the motor 109 to drive the winding roller 110 to rotate. The winding roller 110 winds the lifting rope 112, and drives the support plate 201 to be lifted through the connecting hook 113 and the hanging ear 202. Until the slot 213 inside the support plate 201 is level with the connector 114, start the hydraulic cylinder 106 to make the piston end extend, so that the connector 114 enters the slot 213. During this period, the abutting block 115 is pushed by the inner wall of the slot 213 into the inside of the connector 114 and contracts. Until the abutting block 115 is aligned with the abutting slot 207, the spring 116 pushes the abutting block 115 to extend from the inside of the connector 114, so that the abutting block 115 is inserted into the inside of the abutting slot 207 to complete the locking;

[0036] Then pull out the buffer block 206 outside the limiting plate 205, and release the binding between the hanging hook 113 and the hanging ear 202, and start the hydraulic cylinder 106 to drive the piston end to retract. At this time, the abutting block 115 pushes the inner wall of the abutting slot 207, and pulls the whole support plate 201 to move towards the experimental component 104. Furthermore, the support plate 201 enters the inside of the equipment housing 103, which is convenient for operating and controlling the equipment 104 to perform experimental detection on the gear pump assembly through the experimental component 104;

[0037] Secondly, when it is necessary to release the locking of the abutting block 115 to the abutting slot 207, rotate the knob 211 to drive the lead screw 210 to rotate. The lead screw 210 pushes the outer movable plate 209 and approaches the support plate 201 along the length direction of the movable plate 209. Thus, the extrusion block 212 pushes the abutting block 115 to contract into the inside of the connector 114 again. At this time, the abutting block 115 is separated from the abutting slot 207 and the locking is released.

[0038] The above has described a detailed description of an embodiment of the present utility model, but the content described above is only the preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
