Description

Technical Field

[0001] This utility model relates to the field of vacuum oil pump technology, and in particular to a portable vacuum oil pump trolley. Background Technology

[0002] Vacuum oil pumps are commonly used in settings such as pharmaceutical intermediate laboratories for operations such as gas extraction and establishing a vacuum environment.

[0003] However, in actual use, it is often necessary to move the vacuum oil pump to different workstations to work with equipment such as material tanks. Traditional vacuum oil pumps are fixed and inconvenient to move. Even with a trolley, there are still some shortcomings: First, when connecting the oil pump to the material tank, because the installation height of the delivery pipe is fixed, if the interface position of the material tank is different, additional pipes need to be connected for adaptation, which is cumbersome and the connection efficiency may not be high. Second, when pushing the trolley to move the oil pump or adjusting the height of the oil pump for docking, the overall center of gravity of the trolley is prone to change. Especially during the process of moving the oil pump upward, the existing technology lacks effective counterweight adjustment, which can easily cause the pump to tip over, potentially affecting the safety and normal use of the equipment. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a conveniently movable vacuum oil pump trolley.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable vacuum oil pump trolley, including a body with casters at the bottom, and also including:

[0007] A mounting plate is attached to the vehicle body, and a pump body is fixedly connected to the mounting plate. A delivery pipe is connected to the drive end of the pump body.

[0008] A counterweight cylinder is fixedly connected to a mounting plate. A first sliding plug is slidably connected in the counterweight cylinder. A lifting rod is fixedly connected to the first sliding plug. A counterweight block is fixedly connected to the end of the lifting rod away from the first sliding plug.

[0009] The counterweight cylinder is slidably connected to the vehicle body.

[0010] Preferably, a drive cylinder is fixedly connected to the vehicle body, two sets of drive cylinders are symmetrically arranged, and a second slide plug is slidably connected in the drive cylinder. A push rod is fixedly connected to the second slide plug. The push rod is fixedly connected to the mounting plate. An air supply pipe is fixedly connected to the side wall of the drive cylinder. The end of the air supply pipe away from the drive cylinder is connected to the counterweight cylinder.

[0011] Furthermore, an air supply pipe is fixedly connected to the side wall of the drive cylinder, the air supply pipe is connected to the drive cylinder, and a control valve is connected to both the air supply pipe and the air delivery pipe.

[0012] Preferably, a first spring is fixedly connected to the first slide, and the end of the first spring away from the first slide is fixedly connected to the bottom wall of the counterweight cylinder.

[0013] Furthermore, a second spring is fixedly connected to the second slide, and the end of the second spring away from the second slide is fixedly connected to the inner top wall of the drive cylinder.

[0014] Preferably, an anti-collision rubber ring is fixedly connected to the vehicle body.

[0015] Compared with the prior art, this utility model provides a conveniently movable vacuum oil pump trolley, which has the following advantages:

[0016] 1. This utility model promotes the upward movement of the push rod, mounting plate and pump body by replenishing air to the drive cylinder, so that the pump body's delivery pipe can be adapted to the material tank interface of different heights, eliminating the need for additional pipe splicing, simplifying the operation process and effectively improving the connection efficiency between the pump body and the material tank.

[0017] 2. When the pump body moves upward, the gas delivery pipe introduces gas into the counterweight cylinder, pushing the counterweight block downward, effectively lowering the overall center of gravity of the device. The counterweight block's own weight generates a reverse torque to resist the risk of overturning. At the same time, the gas flow matching design between the drive cylinder and the counterweight cylinder ensures the stability of the pump body after it moves upward, further guaranteeing the device's anti-overturning capability during use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] Reference Figures 1-4 A portable vacuum oil pump trolley, including a body 2 with casters attached to the bottom, and also including:

[0026] Mounting plate 102 is connected to vehicle body 2. Pump body 1 is fixedly connected to mounting plate 102. Delivery pipe 101 is connected to drive end of pump body 1.

[0027] The counterweight cylinder 4 is fixedly connected to the mounting plate 102. A first sliding plug 403 is slidably connected in the counterweight cylinder 4. A lifting rod 501 is fixedly connected to the first sliding plug 403. A counterweight block 5 is fixedly connected to the end of the lifting rod 501 away from the first sliding plug 403.

[0028] The counterweight cylinder 4 is slidably connected to the vehicle body 2.

[0029] It should be noted that the casters at the bottom of vehicle body 2 are commercially available casters with a self-locking function.

[0030] A drive cylinder 3 is fixedly connected to the vehicle body 2. Two sets of drive cylinders 3 are symmetrically arranged, and a second slide plug 304 is slidably connected in the drive cylinder 3. A push rod 302 is fixedly connected to the second slide plug 304. The push rod 302 is fixedly connected to the mounting plate 102. An air supply pipe 6 is fixedly connected to the side wall of the drive cylinder 3. The end of the air supply pipe 6 away from the drive cylinder 3 is connected to the counterweight cylinder 4.

[0031] It should be noted that gas pipe 6 is a flexible hose.

[0032] An air supply pipe 301 is also fixedly connected to the side wall of the drive cylinder 3. The air supply pipe 301 is connected to the drive cylinder 3, and control valves are connected to both the air supply pipe 301 and the air supply pipe 6.

[0033] It should be noted that the control valve is a commercially available solenoid valve, specifically the ZCLF-25 valve.

[0034] Reference Figures 1-4 When in use, the staff manually pushes the vehicle body 2 to move the pump body 1 to the installation position. At this time, the staff uses a portable air pump to add air to the drive cylinder 3. The air pumped in will be injected into the drive cylinder 3 through the air supply pipe 301. At this time, the second sliding plug 304 will push the top rod 302 to move upward, which in turn pushes the mounting plate 102 and the pump body 1 to move upward. When the delivery pipe 101 on the pump body 1 rises to the installation position, the control valve on the air supply pipe 6 is opened. At this time, the input gas will be delivered to the counterweight cylinder 4 through the air supply pipe 6. At this time, the input gas will push the first sliding plug 403 to slide down. The sliding of the first sliding plug 403 will push the boom 501 to slide down, which in turn pushes the counterweight block 5 at the bottom of the boom 501 to slide down.

[0035] This device allows the pump body 1 to be pushed upwards during use, enabling the delivery pipe 101 on the pump body 1 to rise to a suitable installation height. This eliminates the need for additional connecting pipes, improving the connection efficiency between the pump body 1 and the material tank. Simultaneously, as the pump body 1 rises, the counterweight 5 on the counterweight cylinder 4 can be pushed out. By lowering the counterweight 5, the center of gravity of the device can be effectively reduced, thereby ensuring the device's ability to resist overturning.

[0036] It should be noted that the portable air pump can be the commercially available CATEYE PUM-40 air pump.

[0037] It should also be noted that, in order to ensure that the two sets of second sliding plugs 304 can move upward synchronously, when inflating, an air pump tee can be connected to the drive end of the air pump, and the air pump tee can be connected to the two sets of air supply pipes 301 so that when the air pump is inflating, it can push the two sets of second sliding plugs 304 upward simultaneously.

[0038] It should be further explained that the gas flow rate injected into the gas supply pipe 301 is equal to the gas flow rate delivered by the gas delivery pipe 6, thereby ensuring that the second sliding plug 304 will not continue to slide due to the continuous injection of gas during the downward movement of the counterweight 5, thus ensuring that the delivery pipe 101 can be installed stably.

[0039] Reference Figure 3 , Figure 4 A first spring 401 is fixedly connected to the first slide plug 403, and the end of the first spring 401 away from the first slide plug 403 is fixedly connected to the bottom wall of the counterweight cylinder 4.

[0040] The first spring 401 installed on the counterweight cylinder 4 enables the first slider 403 to be quickly reset.

[0041] Reference Figure 3 A second spring 303 is fixedly connected to the second slide 304, and the end of the second spring 303 away from the second slide 304 is fixedly connected to the inner top wall of the drive cylinder 3.

[0042] The second spring 303 installed in the drive cylinder 3 enables the second slide plug 304 to be quickly reset.

[0043] Reference Figure 4 A pressure relief pipe 402 is fixedly connected to the side wall of the counterweight cylinder 4, and a pressure relief valve that can be purchased on the market is connected to the pressure relief pipe 402.

[0044] Reference Figure 1 , Figure 2 In practice, anti-collision rubber rings 201 are fixedly connected to the vehicle body 2.

[0045] By installing anti-collision rubber rings 201 on the vehicle body 2, it can be ensured that the vehicle body 2 is not prone to excessive impact force due to collisions with walls or obstacles in front during movement.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
