Description

Technical Field

[0001] The utility model relates to the technical field of conveyor lines, in particular to a bidirectional hydraulic damping stopper. Background Art

[0002] In modern industrial production and assembly processes, conveyor lines are often used for operations. The pallet carrying the workpiece moves along the roller conveyor driven by the roller conveyor. When the pallet moves to a certain processing station, it is necessary to use a stop device to stop the pallet so that the workpiece stays there for easy operation.

[0003] The existing stopper refers to the patent document CN219408262U. The device proposed in the patent document can reduce the complexity of the device and improve the operating efficiency. However, it is found in actual use that since only one side of the stopper is provided with a sensor, when the pallet is transported from another relative direction, the pallet transported on the other side cannot be stopped in time. For this reason, we provide a bidirectional hydraulic damping stopper to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a bidirectional hydraulic damping stopper, which can achieve the effect of bidirectional stable stopping of the pallet and improve the practicability of the device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bidirectional hydraulic damping stopper, comprising a stopper body and a bidirectional stopper mechanism, the bidirectional stopper mechanism comprising a first cylinder fixedly connected to the inner bottom wall of the stopper body, the output end of the first cylinder being fixedly connected to a bidirectional frame, and second cylinders being installed in the inner walls on both sides of the bidirectional frame.

[0006] The output end of each second cylinder is provided with a hydraulic mechanism, which includes a working frame fixedly connected to the output end of the second cylinder, a hydraulic buffer is installed on the inner wall of the working frame, and a stop block is fixedly connected to the output end of the hydraulic buffer. The stop block is slidably sleeved on the inner wall of the working frame, and an auxiliary mechanism is provided inside the working frame.

[0007] Furthermore, two cavities are opened inside the stopper body, and the inner bottom wall of each cavity is fixedly connected to two guide rods, and the outer surface of each guide rod is slidably sleeved with a slide plate. By providing the guide rods and the slide plate, the stability of the two-way frame during movement can be conveniently improved subsequently, which is beneficial to the stopping and releasing of the pallet.

[0008] Furthermore, the upper surface of each of the slides is fixedly connected to two connecting columns, and the top ends of the four connecting columns are evenly fixedly connected to the bottom surface of the two-way frame. By setting the connecting columns, the two-way frame can be more stable when lifting, which facilitates the stopping and releasing of the pallet.

[0009] Furthermore, two fixed blocks are fixedly connected to the inner wall of the working frame, and sliders are slidably sleeved on the outer surfaces of the two fixed blocks. Telescopic springs are fixedly connected to the side surfaces of the two sliders that are away from each other. The two telescopic springs are respectively sleeved on the outside of the two fixed blocks, and the ends of the two telescopic springs that are away from each other are respectively fixedly connected to the two sides of the inner wall of the working frame. By arranging the fixed blocks, sliders, telescopic springs and connecting rods to cooperate with each other, the impact force generated when the pallet is stopped can be effectively alleviated, which is beneficial to the stable stopping work of the pallet.

[0010] Furthermore, the auxiliary mechanism includes four slide grooves opened on the inner wall of the working frame, and the inner wall of each slide groove is fixedly connected to a limiting rod. The four reserved blocks provided on the outer surface of the stop block are respectively slidably mounted in the four slide grooves. By setting the slide grooves and the limiting rods, the stop block can move more stably and smoothly in the working frame, and the movement range of the stop block will be limited, reducing the degree of rebounding material, which is beneficial to the stabilization of the work of the stop pallet.

[0011] Furthermore, an auxiliary spring is sleeved on the outside of each limit rod, and the two ends of the four auxiliary springs are respectively fixedly connected to four reserved blocks set on the outer surface of the stop block and the inner walls of the four slide grooves. By setting the auxiliary springs, a buffering effect can be achieved, which facilitates the relief of impact force.

[0012] Furthermore, a plurality of sensor mounting grooves are provided on both sides of the outer surface of the stop device body, and a first fixed mounting groove and a second fixed mounting groove are provided on the inner wall of the stop device body. By providing the sensor mounting grooves, sensors can be conveniently installed on both sides of the device, which is beneficial to the two-way stop work of the device. By providing the first fixed mounting groove and the second fixed mounting groove, the device can be conveniently limited and installed at a specified position on the conveyor line.

[0013] Compared with the prior art, the bidirectional hydraulic damping stopper has the following beneficial effects:

[0014] 1. The utility model sets a two-way stopping mechanism, a hydraulic mechanism and an auxiliary mechanism to cooperate with each other, so that the device can stop and release the pallets transported on the front and rear sides, thereby improving the practicality of the device. It is no longer necessary to install multiple stoppers to achieve the two-way stopping effect. In addition, by setting a hydraulic mechanism, the impact force generated by the stopping of the pallet can be effectively alleviated, and the probability of material rebound can be reduced, which is beneficial to the work of stably stopping the material in both directions. The structure is simple and practical.

[0015] 2. The utility model can make the two-way frame more stable when lifting and lowering by setting connecting columns, which is convenient for stopping and releasing the pallet. By setting the fixed block, the sliding block, the telescopic spring and the connecting rod to cooperate with each other, the impact force generated when stopping the pallet can be effectively alleviated, which is beneficial to the stable stopping work of the pallet. The auxiliary spring can have a buffering effect and facilitate the alleviation of impact force. The sensor installation groove can facilitate the installation of sensors on both sides of the device, which is beneficial to the two-way stopping work of the device. The first fixed installation groove and the second fixed installation groove can facilitate the installation of the device at a specified position on the conveyor line.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] As described in the background technology, in order to solve the problem of conveniently stopping the pallet in two directions, this embodiment provides a bidirectional hydraulic damping stopper. The device no longer needs to install multiple stoppers to achieve stable stopping work in two directions. The structure is simple and practical.

[0023] See also Figures 1 to 4This embodiment proposes a bidirectional hydraulic damping stopper, including a stopper body 1 and a bidirectional stopper mechanism 2. Multiple sensor mounting grooves 5 are provided on both sides of the outer surface of the stopper body 1, and a first fixed mounting groove 6 and a second fixed mounting groove 7 are provided on the inner wall of the stopper body 1.

[0024] By providing the sensor installation groove 5, sensors can be conveniently installed on both sides of the device, which is beneficial to the two-way blocking operation of the device. By providing the first fixed installation groove 6 and the second fixed installation groove 7, the device can be conveniently limited and installed at a specified position on the conveyor line.

[0025] The bidirectional stopping mechanism 2 comprises a first cylinder 201 fixedly connected to the inner bottom wall of the stopping device body 1 , a bidirectional frame 202 is fixedly connected to the output end of the first cylinder 201 , and second cylinders 203 are installed in the inner walls on both sides of the bidirectional frame 202 .

[0026] When the first cylinder 201 is started, the two-way frame 202 can be driven to rise or fall. When the two-way frame 202 rises, the pallet can be stopped. When the two-way frame 202 falls, the stopped pallet can be released.

[0027] like Figure 1 As shown, a buffer valve is installed on the upper surface of the second cylinder 203, and one end of the buffer valve is sleeved on the top of the two-way frame 202. The buffer valve can enable the device to adjust the buffer degree of the second cylinder 203 according to the situation, so as to facilitate and stably stop the pallet.

[0028] Two cavities 204 are provided inside the stopper body 1, and the inner bottom wall of each cavity 204 is fixedly connected to two guide rods 205. The outer surface of each guide rod 205 is slidably sleeved with a slide plate 206. By providing the guide rods 205 and the slide plate 206, the stability of the two-way frame 202 during movement can be conveniently improved later, which is beneficial to the stopping and releasing of the tray.

[0029] The upper surface of each slide plate 206 is fixedly connected to two connecting columns 207, and the top ends of the four connecting columns 207 are evenly fixedly connected to the bottom surface of the two-way frame 202. By providing the connecting columns 207, the two-way frame 202 can be more stable when lifting, which facilitates the stopping and releasing of the pallet.

[0030] A hydraulic mechanism 3 is provided at the output end of each second cylinder 203. By setting the hydraulic mechanism 3, the impact force caused by the pallet being stopped can be effectively alleviated, and the probability of material rebound can be reduced. In addition, the hydraulic mechanism 3 set in both directions can stop the pallet being transported in both directions. There is no need to install multiple devices, which makes rational use of resources.

[0031] The hydraulic mechanism 3 includes a working frame 301 fixedly connected to the output end of the second cylinder 203 , a hydraulic buffer 303 is installed on the inner wall of the working frame 301 , and a stop block 302 is fixedly connected to the output end of the hydraulic buffer 303 , and the stop block 302 is slidably sleeved on the inner wall of the working frame 301 .

[0032] By providing the hydraulic buffer 303 , when the pallet collides with the stopping block 302 , the hydraulic buffer 303 can be used for preliminary hydraulic buffering to offset the impact force generated by the collision, thereby facilitating the stable stopping of the pallet by the device.

[0033] Two fixed blocks 304 are fixedly connected to the inner wall of the working frame 301, and sliders 305 are slidably sleeved on the outer surfaces of the two fixed blocks 304. The sides of the two sliders 305 that are away from each other are fixedly connected with telescopic springs 306. The two telescopic springs 306 are respectively sleeved on the outside of the two fixed blocks 304, and the ends of the two telescopic springs 306 that are away from each other are respectively fixedly connected to the two sides of the inner wall of the working frame 301.

[0034] By setting the fixed block 304, the slider 305, the telescopic spring 306 and the connecting rod 307 to cooperate with each other, when the stop block 302 is buffered by the hydraulic buffer 303, the two sliders 305 will slide along the corresponding fixed block 304, and the telescopic spring 306 is set to play an auxiliary buffering effect, so as to more effectively alleviate the impact force generated when stopping the pallet, which is beneficial to the stable stopping work of the pallet.

[0035] The working frame 301 is provided with an auxiliary mechanism 4 inside. The auxiliary mechanism 4 includes four slide grooves 401 opened on the inner wall of the working frame 301. The inner wall of each slide groove 401 is fixedly connected to a limit rod 402. The four reserved blocks provided on the outer surface of the stop block 302 are respectively slidably sleeved in the four slide grooves 401.

[0036] By setting the slide groove 401 and the limit rod 402, the stop block 302 can move more stably and smoothly in the working frame 301, and the movement range of the stop block 302 will be limited, which can reduce the degree of rebounding materials and is beneficial to the stable operation of the stop pallet.

[0037] An auxiliary spring 403 is sleeved on the outside of each limit rod 402, and the two ends of the four auxiliary springs 403 are respectively fixedly connected to the four reserved blocks set on the outer surface of the stop block 302 and the inner walls of the four slide grooves 401. By setting the auxiliary springs 403, a buffering effect can be achieved, which facilitates the alleviation of impact force.

[0038] Working principle: When in use, multiple sensors can be installed on both sides of the device through the sensor installation slot 5, and then the device can be installed at the specified position on the conveyor line through the first fixed installation slot 6 and the second fixed installation slot 7. When the sensor detects a pallet that needs to be stopped, the first cylinder 201 will control the two-way frame 202 to rise to a suitable position, and then the pallet will collide with the stop block 302. When the pallet collides with the stop block 302, it can be initially buffered by the hydraulic buffer 303, and further stopped by the second cylinder 203. It should be noted that the buffering capacity of the second cylinder 203 can be adjusted by the buffer valve arranged on the upper surface of the second cylinder 203 to avoid rebound when the pallet is stopped. At the same time, the telescopic spring 306 and the auxiliary mechanism 4 inside the working frame 301 can also alleviate the impact force caused by the collision, which is beneficial to the stable stopping work. When the stopped pallet needs to be released, the first cylinder 201 can be used to control the two-way frame 202 to descend to the appropriate position. At the same time, the external force of the second cylinder 203 and the stopping block 302 will be cancelled, so the second cylinder 203 and the stopping block 302 will be automatically reset, which is convenient for the next stopping work. The second cylinder 203 is installed on both sides of the device, and the output end of each second cylinder 203 is provided with a hydraulic mechanism 3. Therefore, the device can stop the pallets transported in two corresponding directions without installing multiple devices, which allocates resources more reasonably and has a simple and practical structure.
