Description

Technical Field

[0001] This utility model relates to the field of unloading clamp technology, specifically a clamp for unloading barrelled raw materials. Background Technology

[0002] Currently, most warehouses, docks, and chemical plants handle the loading and unloading of materials in oil drums, and the common practice is to use manual labor in conjunction with forklifts. Oil drums containing materials can weigh over 200 kilograms. Therefore, during handling, workers must lay the drums horizontally on the ground, manually roll them onto a special pallet, stand them upright, and then drive a forklift to push the drums to their destination. Afterward, workers must manually lift the drums back up. This method makes stacking impossible and significantly increases the labor intensity for workers.

[0003] Chinese utility model patent CN207175381U discloses an oil drum loading and unloading device for a forklift, including a horizontal forklift sleeve with slots for inserting forklift arms. A vertical column is fixedly connected to the forklift sleeve, and a plurality of oil drum clamps for clamping oil drums are fixedly connected to the end of the column away from the forklift sleeve. The side of the oil drum clamps near the forklift sleeve is provided with an abutment frame for abutting against the oil drum, and the abutment frame is fixedly connected to the column.

[0004] However, the oil drum clamp of the oil drum loading and unloading device for forklifts is fixedly connected to the rotating block and its position is relatively fixed. This structure cannot be well adapted and clamped for oil drums of different diameters, which greatly limits the device's loading and unloading capacity for oil drums of various specifications. Therefore, a barrel-type raw material unloading clamp is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a barrel-type raw material unloading clamp with advantages such as strong adaptability, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A barrel-type raw material unloading clamp includes a forklift sleeve, a column fixedly connected to the top of the forklift sleeve, a barrel clamp rotatably installed inside the column and extending to the outside of the column, and an adjusting rod inserted into the outside of the column and extending into the inside of the barrel clamp. The outside of the column is provided with a clamping structure for clamping barrels of different diameters.

[0008] The clamping structure includes a mounting box fixedly connected to the outside of the column. A bidirectional screw extending to the outside of the mounting box is rotatably connected inside the mounting box. Threaded blocks are threadedly connected to the left and right sides of the outside of the bidirectional screw. A connecting block is fixedly connected to the outside of the threaded block. A clamping block is fixedly connected to the outside of the connecting block. A magnet is fixedly installed inside the clamping block.

[0009] Furthermore, the forklift sleeve, column, oil drum clamp, and adjusting rod are all in two sets. The mounting box is fixedly connected to the outside of the two sets of columns, and the inside of the column has a number of adjusting holes that are adapted to the adjusting rod.

[0010] Furthermore, a bearing adapted to the bidirectional screw is fixedly installed inside the mounting box, and a knob is fixedly connected to the end of the bidirectional screw away from the mounting box.

[0011] Furthermore, the number of threaded blocks, connecting blocks, clamping blocks, and magnet blocks are all in two sets, and the two sets of clamping blocks are symmetrically distributed on the outside of the bidirectional screw.

[0012] Furthermore, the back of the threaded block is fixedly connected to a slider extending into the interior of the mounting box, and the interior of the mounting box is provided with a sliding groove that matches the slider, and the slider and the sliding groove are slidably connected.

[0013] Furthermore, the forklift sleeve is provided with a limiting structure extending into its interior. The limiting structure includes an adjusting screw rotatably connected to the top of the forklift sleeve and extending into its interior. The bottom end of the adjusting screw is rotatably connected to a clamping plate, and the top end of the clamping plate is fixedly connected to a limiting rod extending into the upper surface of the forklift sleeve. There are two limiting rods, and both limiting rods are slidably connected to the interior of the forklift sleeve.

[0014] Furthermore, a reinforcing rib is fixedly connected between the forklift sleeve and the column, and the number of the reinforcing ribs is two sets.

[0015] Furthermore, two reinforcing arms are fixedly connected between the two sets of forklift sleeves. A steel wire rope is fixedly connected to the outside of the right reinforcing arm, and a hook is fixedly connected to the end of the steel wire rope away from the reinforcing arm.

[0016] Compared with the prior art, this utility model provides a clamp for unloading raw materials in drums, which has the following advantages:

[0017] 1. This drum-type raw material unloading clamp uses a knob to rotate a two-way screw, which causes the threaded block to move the clamping block along the axial direction of the two-way screw, thus adapting to oil drums of different diameters. When clamping the oil drum, the magnetic block generates a strong adsorption force, making the clamping block fit more tightly against the outer wall of the oil drum, effectively preventing the oil drum from slipping during loading and unloading, improving the safety and stability of loading and unloading, and can load and unload oil drums of various specifications, greatly improving the versatility of the clamp.

[0018] 2. This barrel-type raw material unloading clamp allows the clamping plate to move downwards by rotating the adjusting screw, thereby tightly clamping the forklift arm. The clamping plate is slidably connected to the inside of the forklift sleeve by a limit rod, which guides the movement of the clamping plate and prevents it from shifting during movement. This ensures the stability of the limit structure, makes the connection between the forklift sleeve and the forklift arm more secure, and reduces the safety hazards caused by clamp shaking during loading and unloading.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3 The barrel-type raw material unloading clamp in this embodiment includes a forklift sleeve 1, a column 2 fixedly connected to the top of the forklift sleeve 1, a barrel clamp 3 rotatably installed inside the column 2 and extending to its outside, and an adjusting rod 4 inserted into the outside of the column 2 and extending into the inside of the barrel clamp 3. The outside of the column 2 is provided with a clamping structure 6 for clamping barrels of different diameters.

[0025] The clamping structure 6 includes a mounting box 61 fixedly connected to the outside of the column 2. A bidirectional screw 62 extending outwards is rotatably connected inside the mounting box 61. Threaded blocks 64 are threadedly connected to both the left and right sides of the bidirectional screw 62. A connecting block 65 is fixedly connected to the outside of the threaded block 64, and a clamping block 66 is fixedly connected to the outside of the connecting block 65. A magnet 67 is fixedly installed inside the clamping block 66. When clamping the oil drum, the magnet 67 generates a strong adsorption force, causing the clamping block 66 to fit more tightly against the outer wall of the oil drum, effectively preventing the oil drum from slipping during loading and unloading, and improving the safety and stability of loading and unloading.

[0026] Specifically, there are two sets of forklift sleeve 1, upright column 2, oil drum clamp 3, and adjusting rod 4. The mounting box 61 is fixedly connected to the outside of the two sets of upright columns 2. The interior of the upright column 2 has multiple adjusting holes 5 that are adapted to the adjusting rod 4. By opening multiple adjusting holes 5 inside the upright column 2 that are adapted to the adjusting rod 4, the operator can flexibly adjust the height or angle of the oil drum clamp 3 according to actual needs by inserting the adjusting rod 4 into the adjusting holes 5 at different positions, further improving the adaptability of the oil drum clamp 3 to different working conditions and oil drum placement.

[0027] It should be noted that a bearing compatible with the bidirectional screw 62 is fixedly installed inside the mounting box 61, and a knob 63 is fixedly connected to the end of the bidirectional screw 62 away from the mounting box 61. There are two sets of threaded blocks 64, connecting blocks 65, clamping blocks 66, and magnetic blocks 67. The two sets of clamping blocks 66 are symmetrically distributed on the outside of the bidirectional screw 62. When the bidirectional screw 62 rotates, the two sets of threaded blocks 64 move towards or away from each other along the bidirectional screw 62, and the connecting block 65 drives the two sets of clamping blocks 66 to move closer or further apart, thereby achieving clamping of oil drums of different diameters and expanding the applicability of the oil drum clamp 3.

[0028] It is worth mentioning that a slider extending into the mounting box 61 is fixedly connected to the back of the threaded block 64. The mounting box 61 has a groove inside that matches the slider, and the slider and the groove are slidably connected. When the bidirectional screw 62 rotates and drives the threaded block 64 to move, the slider slides in the groove, providing precise guidance for the movement of the threaded block 64 and preventing the threaded block 64 from rotating with the bidirectional screw 62. This ensures the stability and accuracy of the movement of the clamping block 66, making the clamping action more reliable.

[0029] Please see Figure 1 and Figure 3In this embodiment, a limiting structure 7 extending into the forklift sleeve 1 is provided on its exterior. The limiting structure 7 includes an adjusting screw 71 rotatably connected to the top of the forklift sleeve 1 and extending into its interior. A clamping plate 72 is rotatably connected to the bottom end of the adjusting screw 71, and a limiting rod 73 extending into the upper surface of the forklift sleeve 1 is fixedly connected to the top end of the clamping plate 72. There are two limiting rods 73, both of which are slidably connected inside the forklift sleeve 1. When the forklift sleeve 1 is installed on the forklift arm, rotating the adjusting screw 71 can move the clamping plate 72 downward, thereby tightly clamping the forklift arm. The limiting rod 73, slidably connected inside the forklift sleeve 1, guides the movement of the clamping plate 72, preventing the clamping plate 72 from shifting during movement, ensuring the stability of the limiting structure 7, making the connection between the forklift sleeve 1 and the forklift arm more secure, and reducing the safety hazards caused by the shaking of the clamp during loading and unloading.

[0030] The forklift sleeve 1 and the upright column 2 are fixedly connected by two sets of reinforcing ribs 8. Two reinforcing arms 9 are fixedly connected between the forklift sleeves 1, and the outside of the right reinforcing arm 9 is fixedly connected to a hook by a steel wire rope.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, the forklift sleeve 1 is installed on the fork teeth of the forklift. The forklift arm is fixed inside the forklift sleeve 1 by adjusting the screw 71 and the clamp 72 to ensure the stability of the device during loading and unloading. The overall stability of the device is further enhanced by the reinforcing ribs 8 and the reinforcing arm 9 to ensure the device's firmness during loading and unloading. According to the height of the oil drum, the adjusting rod 4 is inserted into the adjusting hole 5 inside the column 2 to adjust the position of the oil drum clamp 3 so that it can adapt to oil drums of different heights. The adjusting rod 4 is adapted to multiple adjusting holes 5 inside the column 2, providing a variety of height adjustment options. According to the diameter of the oil drum, the double-acting screw 62 is rotated by the knob 63. The two ends are respectively provided with left-hand and right-hand threads. The threaded block 64 drives the clamping block 66 to move relative to each other along the axial direction of the bidirectional screw 62, thereby adjusting the distance between the clamping blocks 66 to accommodate oil drums of different diameters. When the oil drum is placed between the two clamping blocks 66, the magnet block 67 on the inner side of the clamping block 66 contacts the oil drum, enhancing the friction between the clamping block 66 and the oil drum and ensuring the clamping effect. During loading and unloading, the forklift operator can control the opening and closing of the oil drum clamp 3 through the hydraulic system of the forklift to realize the clamping and release of the oil drum. By adjusting the adjustment function of the insertion rod 4 and the bidirectional screw 62, the device can adapt to oil drums of various specifications, improving loading and unloading efficiency and applicability.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
