Description

Technical Field

[0001] The utility model relates to the technical field of engineering material production, in particular to a barrel locking device. Background Art

[0002] For the production of coatings, the raw materials must first be placed in a barrel according to proportion, and then the barrel must be moved to a position where it docks with a mixer and lifted, so that the mixer can stir the raw materials in the barrel to mix them evenly, and then the barrel must be moved to a position where it docks with a press and lifted, so that the press can discharge the raw materials in the barrel from the bottom of the barrel.

[0003] At present, in the process of lifting the barrel, in order to prevent the barrel from moving and being misaligned with the mixer or the press, a barrel locking device is set to fix the barrel, but most of the existing barrel locking devices are simple in structure, and the operator is mostly required to manually lock the barrel, which is not convenient for automatically locking the barrel during the barrel lifting process, and is troublesome and laborious to use. Therefore, in view of the above technical problems, a barrel locking device is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model proposes a barrel locking device, which is convenient for automatically locking and fixing the barrel during the barrel lifting process, and is easy to use and labor-saving.

[0005] Bucket locking device, including:

[0006] A base, with a frame arranged on the top;

[0007] A lifting seat, both ends of which are connected to the frame through hydraulic telescopic columns so that the lifting seat can slide in a vertical direction;

[0008] A material bucket, which can be placed on the base and is located above the lifting seat; and

[0009] The locking mechanism includes a top plate, a spring, two groups of clamping plates and a transmission assembly. The top plate can be slidably arranged on the lifting seat in a vertical direction, can contact the bottom of the barrel, and can be flush with the top surface of the lifting seat when under pressure. The two ends of the spring respectively abut against the lifting seat and the bottom surface of the top plate. The two groups of clamping plates can be slidably arranged on the lifting seat along the radial direction of the barrel. The barrel is located between the two groups of clamping plates. The top plate is connected to the two groups of clamping plates through the transmission assembly to convert the sliding of the top plate into relative approach or distance movement of the two groups of clamping plates.

[0010] The beneficial effects of the above barrel locking device are:

[0011] When lifting the material barrel, the lifting seat is driven to move upward by controlling the contraction of the hydraulic telescopic rod. The upward movement of the lifting seat drives the top plate to move upward. When the top plate moves upward and contacts the bottom of the material barrel, the top plate stops moving upward and moves downward relative to the lifting seat. The downward movement of the top plate causes the spring to contract under pressure and drives the two groups of clamping plates to move relatively close to each other through the transmission assembly. When the lifting seat moves upward and contacts the bottom of the material barrel, the two groups of clamping plates move relatively close to each other and contact the material barrel to lock the material barrel. At this time, the lifting seat continues to move upward to drive the material barrel to move upward. The two groups of clamping plates are moved relatively close to each other by relying on the dead weight of the material barrel to lock the material barrel. This is convenient for automatically locking and fixing the material barrel during the lifting process of the material barrel, and is convenient and labor-saving to use.

[0012] In one embodiment, a first guide groove is provided at the top of the lifting seat, and two sets of limit shafts are relatively provided at the bottom of the top plate. The two sets of limit shafts can be slidably provided in the first guide groove along the vertical direction, and the two sets of limit shafts are sleeved with the springs, and the two ends of the springs respectively abut against the bottom surface of the first guide groove and the bottom surface of the top plate. The stability of the top plate sliding in the vertical direction can be improved by providing the limit shaft, and the spring sleeved on the limit shaft can limit the contraction of the spring, thereby avoiding the situation where the spring is skewed due to contraction, and extending the service life of the spring.

[0013] In one embodiment, the transmission assembly includes a bidirectional screw, a rack and a gear; the bidirectional screw is rotatably arranged in the first guide groove, and the two ends are respectively threadedly connected with the two groups of the clamping plates, the gear is arranged on the bidirectional screw, and the rack is arranged at the bottom end of the top plate, and the rack is meshed with the gear. When the top plate moves relative to the lifting seat, the top plate drives the rack to move, the rack moves and meshes with the gear to drive the gear to rotate, the gear rotation can drive the bidirectional screw to rotate, the bidirectional screw rotates and cooperates with the two groups of clamping plate threads to drive the two groups of clamping plates to move relatively close or away, and it is convenient to drive the two groups of clamping plates to move relatively close or away.

[0014] In one embodiment, the two groups of clamping plates are provided with connecting columns on the opposite sides, and the two groups of connecting columns are provided with guide seats at the bottom ends. The two groups of guide seats can be radially slidable along the barrel and arranged in the first guide groove, and are respectively threadedly connected with the two ends of the bidirectional screw. The rotation of the bidirectional screw and the threaded cooperation of the two groups of guide seats can drive the two groups of clamping plates to move relatively close or away through the connecting columns, and the cooperation of the two groups of guide seats and the first guide groove can improve the stability of the two groups of clamping plates when they move relatively close or away.

[0015] In one embodiment, the locking mechanism further includes an adjusting screw; the top ends of the two groups of guide seats are provided with a second guide groove, the bottom ends of the two groups of connecting columns are respectively slidable along the radial direction of the barrel in the two groups of the second guide grooves, the adjusting screws are rotatably provided in the two groups of the second guide grooves, and the adjusting screws are threadedly connected to the connecting columns. By rotating the two groups of adjusting screws and the connecting column threads respectively, the connecting column is driven to drive the clamping plate to move the same distance closer to or away from the barrel, so as to facilitate the adjustment of the initial spacing between the two groups of clamping plates, thereby facilitating the automatic locking of barrels of different sizes, thereby improving the practicality of the device.

[0016] In one embodiment, the two groups of clamping plates are provided with a clamping block on the opposite side, and the two groups of connecting columns are provided with a clamping slot at the top, and the clamping block can be clamped in the clamping slot. The clamping plate and the connecting column are connected by a clamping connection, and the clamping plate is easy to install and remove, so that it is convenient to replace the clamping plate of the appropriate size according to the barrels of different sizes, so as to ensure the stability of the clamping plate locking the barrels of different sizes.

[0017] In one embodiment, a receiving groove is provided on the top surface of the base, the lifting seat is located in the receiving groove, and the top surface is flush with the top surface of the base. By providing the receiving groove, the top surface of the lifting seat is flush with the top surface of the base, so that the material barrel can be moved to or removed from the top of the lifting seat, which is convenient for use.

[0018] In one embodiment, a rubber pad is provided on the top of the top plate, which can prevent the top plate from causing squeezing damage to the bottom of the barrel, and the rubber pad can increase the friction between the top plate and the bottom of the barrel, further improving the stability of the lifting barrel.

[0029] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0030] See also Figures 1 to 3 In one embodiment, a barrel locking device includes a base 10, a lifting seat 20, a barrel 30 and a locking mechanism 40.

[0031] Among them, a frame 101 is set at the top of the base 10; the two ends of the lifting seat 20 are connected to the frame 101 through hydraulic telescopic columns 201, so that the lifting seat 20 can slide in the vertical direction; the barrel 30 can be placed on the base 10 and is located above the lifting seat 20; the locking mechanism 40 includes a top plate 401, a spring 402, two groups of clamping plates 405 and a transmission assembly, the top plate 401 can be slidably set on the lifting seat 20 in the vertical direction, and can contact the bottom of the barrel 30, and when under pressure, it can be flush with the top surface of the lifting seat 20, the two ends of the spring 402 respectively press against the bottom surface of the lifting seat 20 and the top plate 401, the two groups of clamping plates 405 can be set on the lifting seat 20 to slide radially along the barrel 30, the barrel 30 is located between the two groups of clamping plates 405, and the top plate 401 is connected to the two groups of clamping plates 405 through a transmission assembly to convert the sliding of the top plate 401 into a relative approach or distance movement of the two groups of clamping plates 405.

[0032] In the above embodiment, when lifting the material barrel 30, the lifting seat 20 is driven to move upward by controlling the hydraulic telescopic column 201 to contract, and the lifting seat 20 moves upward to drive the top plate 401 to move upward. When the top plate 401 moves upward and contacts the bottom of the material barrel 30, the top plate 401 stops moving upward and moves downward relative to the lifting seat 20. The downward movement of the top plate 401 causes the spring 402 to be compressed and contracted, and drives the two groups of clamping plates 405 to move relatively close to each other through the transmission component. When the lifting seat 20 moves upward and contacts the bottom of the material barrel 30, the two groups of clamping plates 405 move relatively close to each other and contact the material barrel 30 to lock the material barrel 30. At this time, the lifting seat 20 continues to move upward to drive the material barrel 30 to move upward, and the weight of the material barrel 30 causes the two groups of clamping plates 405 to move relatively close to each other. The clamping plate 405 moves relatively close to lock the barrel 30, which is convenient for automatically locking the barrel 30 during the lifting process of the barrel 30. It is convenient and labor-saving to use. When it is necessary to cancel the locking of the barrel 30, the lifting seat 20 is driven to move downward by controlling the extension of the hydraulic telescopic column 201. When the lifting seat 20 moves downward, it drives the barrel 30 to move downward so that the barrel 30 is placed on the base 10, and the lifting seat 20 moves downward and separates from the barrel 30. At this time, the reaction force of the spring 402 causes the top plate 401 to move upward relative to the lifting seat 20. The top plate 401 moves upward to drive the two groups of clamping plates 405 to move relatively away from the barrel 30 through the transmission assembly, thereby canceling the locking of the barrel 30, which is convenient for automatically canceling the locking of the barrel 30.

[0033] On the basis of the above embodiment, further, a first guide groove 202 is opened at the top of the lifting seat 20, and two groups of limit shafts 403 are relatively arranged at the bottom end of the top plate 401. The two groups of limit shafts 403 can be slidably arranged in the first guide groove 202 along the vertical direction. Springs 402 are both sleeved on the two groups of limit shafts 403, and the two ends of the spring 402 respectively resist the bottom surface of the first guide groove 202 and the bottom surface of the top plate 401.

[0034] The limiting shaft 403 can be provided to improve the stability of the top plate 401 sliding in the vertical direction, and the spring 402 is sleeved on the limiting shaft 403 to limit the contraction of the spring 402, thereby preventing the spring 402 from being skewed due to contraction and extending the service life of the spring 402.

[0035] See also Figure 2 and Figure 3 In one embodiment, the transmission assembly includes a bidirectional screw 406, a rack 404 and a gear 4061; the bidirectional screw 406 is rotatably arranged in the first guide groove 202, and its two ends are respectively threadedly connected to the two sets of clamping plates 405, a gear 4061 is arranged on the bidirectional screw 406, and a rack 404 is arranged at the bottom end of the top plate 401, and the rack 404 is meshed with the gear 4061.

[0036] In the above embodiment, when the top plate 401 moves downward relative to the lifting seat 20, the top plate 401 drives the rack 404 to move downward, and the rack 404 moves downward and meshes with the gear 4061 to drive the gear 4061 to rotate. The rotation of the gear 4061 drives the bidirectional screw 406 to rotate. The rotation of the bidirectional screw 406 and the threaded cooperation of the two groups of clamping plates 405 can drive the two groups of clamping plates 405 to move relatively close to each other. Conversely, when the top plate 401 moves upward relative to the lifting seat 20, the top plate 401 drives the rack 404 to move upward and meshes with the gear 4061 to drive the gear 4061 to rotate in the opposite direction. The reverse rotation of the gear 4061 drives the bidirectional screw 406 to rotate in the opposite direction and cooperates with the threads of the two clamping plates 405 to drive the two groups of clamping plates 405 to move relatively away from each other, making it convenient to drive the two groups of clamping plates 405 to move relatively close to or away from each other.

[0037] See also Figures 2 to 4 In one embodiment, connecting columns 407 are provided on the opposite sides of the two sets of clamping plates 405, and guide seats 408 are provided at the bottom ends of the two sets of connecting columns 407. The two sets of guide seats 408 can be radially slidably arranged in the first guide groove 202 along the barrel 30, and are respectively threadedly connected to the two ends of the bidirectional screw 406.

[0038] In the above embodiment, the bidirectional screw 406 rotates and cooperates with the two groups of guide seats 408 threads to drive the two groups of guide seats 408 to drive the two groups of clamping plates 405 to move relatively close or away through the connecting column 407. The two groups of guide seats 408 cooperate with the first guide groove 202 to improve the stability of the two groups of clamping plates 405 when they move relatively close or away.

[0039] On the basis of the above embodiment, the locking mechanism 40 further includes an adjusting screw 409; the top ends of the two groups of guide seats 408 are each provided with a second guide groove 4081, and the bottom ends of the two groups of connecting columns 407 are respectively arranged in the two groups of second guide grooves 4081 and can slide radially along the barrel 30, and the two groups of second guide grooves 4081 are both rotatably provided with adjusting screws 409, and the adjusting screws 409 are threadedly connected to the connecting columns 407.

[0040] By rotating the two sets of adjusting screws 409 and the connecting column 407 threads respectively, driving the connecting column 407 to drive the clamping plate 405 to move the same distance closer to or away from the barrel 30, it is convenient to adjust the initial spacing of the two sets of clamping plates 405. It can be understood that the larger the size of the barrel 30, the larger the initial spacing of the two sets of clamping plates 405. Conversely, the smaller the size of the barrel 30, the smaller the initial spacing of the two sets of clamping plates 405. This facilitates the automatic locking of barrels 30 of different sizes and improves the practicality of the device.

[0041] On the basis of the above embodiment, further, the two groups of clamping plates 405 are provided with a clamping block 4051 on the opposite sides, and the two groups of connecting posts 407 are provided with a clamping groove 4071 at the top, and the clamping block 4051 can be clamped in the clamping groove 4071. The clamping plate 405 and the connecting post 407 are connected by a clamping connection, and the clamping plate 405 is easy to install and remove, so that it is convenient to replace the clamping plate 405 of the appropriate size according to the barrel 30 of different sizes, so as to ensure the stability of the clamping plate 405 locking the barrel 30 of different sizes.

[0042] See also Figure 1 In one embodiment, a receiving groove 102 is provided on the top surface of the base 10, and the lifting seat 20 is located in the receiving groove 102, and the top surface is flush with the top surface of the base 10. By providing the receiving groove 102, the top surface of the lifting seat 20 is flush with the top surface of the base 10, so that the bucket 30 can be moved to the top of the lifting seat 20 or removed from the top of the lifting seat 20, which is convenient for use.

[0043] See also Figure 1 In one embodiment, a rubber pad 4011 is provided on the top of the top plate 401. The rubber pad 4011 can prevent the top plate 401 from causing squeezing damage to the bottom of the barrel 30, and the rubber pad 4011 can increase the friction between the top plate 401 and the bottom of the barrel 30, further improving the stability of lifting the barrel 30.

[0044] The specific implementation of the above barrel locking device is as follows:

[0045] When lifting the barrel 30, the barrel 30 is moved above the top plate 401 and located between the two sets of clamping plates 405, and then the hydraulic telescopic column 201 is controlled to contract to drive the lifting seat 20 to move upward. The lifting seat 20 moves upward to drive the top plate 401 to move upward. When the top plate 401 moves upward and contacts the bottom of the barrel 30, the top plate 401 stops moving upward and moves downward relative to the lifting seat 20. The top plate 401 moves downward to compress the spring 402 and contract it, and the rack 404 moves downward. The rack 404 moves downward and meshes with the gear 4061 to drive the gear 4061 to rotate. The rotation of the gear 4061 drives the bidirectional screw 406 to rotate, and the rotation of the bidirectional screw 406 and the two sets of The threaded cooperation of the guide seat 408 can drive the two groups of guide seats 408 to drive the two groups of clamping plates 405 to move relatively close to each other through the connecting column 407. When the lifting seat 20 moves upward and contacts the bottom of the barrel 30, the two groups of clamping plates 405 move relatively close to each other and contact the barrel 30 to lock the barrel 30. At this time, the lifting seat 20 continues to move upward to drive the barrel 30 to move upward. At this time, the weight of the barrel 30 keeps the top plate 401 stationary, thereby keeping the two groups of clamping plates 405 in a locked state. The weight of the barrel 30 is used to make the two groups of clamping plates 405 move relatively close to each other to lock the barrel 30, so that the barrel 30 can be automatically locked during the lifting process of the barrel 30, which is convenient and labor-saving to use.

[0046] When it is necessary to cancel the lock on the barrel 30, the hydraulic telescopic column 201 is controlled to extend to drive the lifting seat 20 to move downward. When the lifting seat 20 moves downward, it drives the barrel 30 to move downward so that the barrel 30 is placed on the base 10, and the lifting seat 20 moves downward and separates from the barrel 30. At this time, the reaction force of the spring 402 causes the top plate 401 to move upward relative to the lifting seat 20. The upward movement of the top plate 401 can drive the rack 404 to move upward, and the rack 404 moves upward to engage with the gear 4061 to drive the gear 4061 to rotate in the opposite direction. The reverse rotation of the gear 4061 drives the bidirectional screw 406 to rotate in the opposite direction and cooperate with the two sets of guide seats 408 threads to drive the two sets of guide seats 408 to drive the two sets of clamping plates 405 to move relatively away from the barrel 30 through the connecting column 407 to separate from the barrel 30, thereby canceling the lock on the barrel 30, which is convenient for automatically canceling the lock on the barrel 30.
