Description

Technical Field

[0001] The utility model relates to the technical field of transfer equipment, in particular to a tank transfer clamping device. Background Art

[0002] The tanks that hold raw materials are generally cylindrical metal tanks. Whether fully loaded or empty, the tanks are heavy. During storage, the tanks often need to be moved to ensure they are in a reasonable position within the warehouse. To reduce the labor intensity of workers, transfer and adjustment are often performed with the aid of external equipment. For example, the Chinese utility model patent with the authorization announcement number CN 221251257U states that the normal use of the tanks is premised on the rims of the tanks being transferred being intact and having sufficient strength. Furthermore, during transfer, the top of the tanks is clamped by the clamping portion, and then an outward force is applied to the middle and lower parts or the bottom of the tanks by the push rod. Since the rims of the tanks are relatively small, this process can easily lead to unstable gripping and the tanks falling off. If the tanks are relatively heavy, the rims of the tanks may also be damaged. In addition, the support frame used to stabilize the transfer vehicle is not adjustable in length. When the tanks are clamped, the center of gravity of the entire transfer vehicle changes, and the support frame cannot change or adjust the instability caused by the low center of gravity. Utility Model Content

[0003] The technical problem to be solved by the present invention is that the tank body used in the clamping part of the existing transfer vehicle must require the top edge of the tank body to be intact and strong enough, and the bottom of the transfer vehicle cannot change the support point spacing on the ground, and cannot change the center of gravity position or the size of the torque during use to make the transfer vehicle more stable. In view of the above-mentioned defects of the prior art, a tank body transfer clamping device is provided.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A tank transfer clamping device is constructed, comprising a base, a fixed arm and a movable arm provided on the upper side of the base, the movable arm being connected to a fixed wall via a first telescopic electric cylinder, and the inclination angle of the movable arm being controlled by the first telescopic electric cylinder; wherein a clamping assembly for clamping the tank is provided on the movable arm; a retractable support frame is provided on the side of the base close to the movable arm, and a counterweight block is provided at the end of the support frame. When clamping the tank, the support frame is retracted to drive the position of the counterweight block to change, so as to increase the stability of the holding device.

[0006] Preferably, a universal wheel is provided on the lower side of the bottom of the base away from the end of the movable arm, and a receiving cavity with an open end is provided on both sides of the base along the length direction of the base. One end of the support frame can be telescopically inserted into the receiving cavity, and a roller is provided on the lower side of the end of the support frame located outside the receiving cavity.

[0007] Preferably, the base is provided with a positioning hole, and the support frame is provided with a plurality of positioning holes along the length direction of the support frame. During positioning, the positioning holes on the support frame are coaxial with the positioning holes on the base and are connected by a pin shaft.

[0008] Preferably, the movable arm includes an inner arm and an outer arm, wherein the lower end of the inner arm is hingedly connected to the upper side of the base, the movable arm is sleeved on the inner arm, and the movable arm controls the lifting and lowering of the movable arm through a third telescopic electric cylinder arranged in the inner arm.

[0009] Preferably, the clamping assembly includes a traction part, a first support part and a second support part; one end of the traction part is hingedly provided on the outer arm, and the other end is hingedly provided with a front contact surface, and a second telescopic electric cylinder is provided between the upper side of the traction part and the top of the outer arm, and the inclination angle of the traction part is controlled by the second telescopic electric cylinder; the first support part is provided close to the lower end of the outer arm, and the second support part is provided at the lower end of the inner arm, and the first support part and the second support part both have a rear contact surface, and the front contact surface and the rear contact surface are provided opposite to each other.

[0010] It should be noted that a fixed support end is further provided on the outer arm opposite to the front contact surface of the traction part. When in use, the fixed support end and the front contact surface of the traction part jointly clamp the top of the tank body.

[0011] Preferably, first hinge terminals are provided on the opposite surfaces of the fixed arm and the inner arm, and both ends of the first telescopic electric cylinder are hingedly connected to the first hinge terminals respectively; a sliding hole is provided on the outer arm, and the first hinge terminal provided on the inner arm is located in the sliding hole, so that when the inner arm is extended or retracted, the first intersection terminal on the inner arm slides relative to the slider; a notch is provided at the lower end of the outer arm on the side opposite to the sliding hole, and the second support part can enter or leave the notch when the outer wall descends or rises.

[0012] Preferably, the first support part and the second support part both include an electric telescopic rod, and an arc-shaped end is fixedly provided at the distal end of the electric telescopic rod. The end of the arc-shaped end away from the telescopic rod is an arc-shaped surface, and the arc-shaped surface contacts the outer side surface of the supporting tank body to apply tension or support force to the tank body.

[0013] Preferably, in the initial state, the distance between the arc surface of the first support part and the movable arm is smaller than the distance between the arc surface of the second support part and the movable arm. This ensures that during the clamping process, the tank body is first clamped off the ground by the traction part and the second support end, and the traction part cooperates with the second support part at the clamping point to make the traction part have a larger torque.

[0014] The beneficial effects of the present invention are:

[0015] 1. The movable arm of the utility model is connected to the fixed wall through the first telescopic electric cylinder, and the tilt angle of the movable arm is controlled by the first telescopic electric cylinder, so that the center of gravity position of the clamped tank can be automatically changed.

[0016] 2. The base of the utility model is provided with a retractable support frame on one side, and a counterweight block is provided at the end of the support frame. When clamping the tank body, the support frame is retracted to drive the counterweight block to change its position, so as to increase the stability of the holding device and prevent the device from tipping over due to the change of the overall center of gravity or torque caused by the tank body leaving the ground and being in an inclined state.

[0017] 3. The holding process of the utility model is first that during the grasping process, the angle of the movable arm can be changed to pull and tilt the tank body with the bottom side as the fulcrum through the traction part, so that the lower side of the tank body rests on the second support part. During the process of the movable arm continuing to tilt, with the second support part as the fulcrum, the torque of the traction part is in a large state, and the tilting operation of the movable arm and the holding of the tank body are easier.

[0018] 4. The utility model is also provided with a first supporting part on the outer arm of the movable arm. After the traction part cooperates with the second supporting part to lift the tank body off the ground, since the bottom of the tank body is still in a relatively low position, if the tank body needs to be placed on a relatively high platform through the device, the tank body cannot be lifted under the clamping of the traction part and the second supporting part. However, the utility model provides a first supporting part on the outer wall, and the first supporting part can replace the second supporting part and the traction part to support the tank body, so that the tank body can be lifted along with the outer arm to increase the placement height of the tank body.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that, in the present application, as shown in the figure, the base is provided with a universal wheel or roller on one side which is the lower side and the opposite side is on the upper side.

[0027] The transfer device involved in the present invention is mainly used for transferring cylindrical objects such as tanks. The cylindrical objects transferred by the device can be cylindrical tanks with or without rims, and the contact parts during transfer do not damage the tanks.

[0028] The present invention is described below in conjunction with the accompanying drawings. Figure 1-5 The figure shows a tank transfer and clamping device comprising a square plate-shaped base 1, typically made of high-strength steel. A fixed arm 2 and a movable arm 3 are mounted on the upper side of the base 1. The movable arm 3 is connected to the fixed wall 2 via a first telescopic cylinder 4, which controls the tilt angle of the movable arm 3 by extending and retracting the first telescopic cylinder 4.

[0029] In some embodiments, a clamping assembly 5 for clamping the tank body is provided on the movable arm 3, so as to clamp the tank body off the ground and hold it.

[0030] In order to increase the stability of the base, a retractable support frame 6 is provided on the side of the base 1 close to the movable arm 3, and a counterweight block 61 is provided at the end of the support frame 6. When clamping the tank body, the support frame 6 is retracted to drive the counterweight block 61 to change its position to increase the stability of the holding device. In this way, the tank body is on the base 1 and the counterweight block 61 is away from the tank body, which can prevent the base 1 from tipping over due to the heavy weight of the tank body.

[0031] like Figure 5 As shown, a universal wheel is provided on the lower side of one end of the bottom of the base 1 away from the movable arm 3, and a receiving cavity 11 with an open end is provided on both sides of the base 1 along the length direction of the base 1. One end of the support frame 6 can be telescopically inserted into the receiving cavity 11, and the support frame 6 is fixed by a detachable pin 62, and a roller is provided on the lower side of the end of the support frame 6 located outside the receiving cavity 11.

[0032] Specifically, a positioning hole 12 is provided on the base 1, and a plurality of positioning holes 63 are provided on the support frame 6 along the length direction of the support frame 6. When positioning, the extension length of the support frame 6 is selected according to the weight of the can to be clamped, and the positioning hole 63 at the appropriate position on the support frame 6 is coaxially aligned with the positioning hole 12 on the base 1, and connected by a pin shaft 12.

[0033] The movable arm 3 in the above embodiment comprises an inner arm 31 and an outer arm 32. The outer arm 32 is hollow and tubular. An open slot 311 is provided at the top of the inner wall 31. A third telescopic cylinder 33 is housed within the slot. The third telescopic cylinder 33 controls the depth to which the outer arm 32 fits within the inner wall 31. The lower end of the inner arm 31 is hingedly connected to the upper side of the base 1, allowing the movable arm 3 to rotate or swing about the hinge axis. The outer arm 32 fits within the inner arm, and its elevation is controlled by the third telescopic cylinder 33, which is located within the inner arm 31.

[0034] Specifically, the clamping assembly 5 includes a traction portion 51, a first support portion 52 and a second support portion 53; one end of the traction portion 51 is hingedly provided on the outer arm 32, and the other end is bent in an L shape, and a front contact surface 511 is hingedly provided on the inner side of the L shape. The front contact surface 511 can only make a small range of angle changes under the action of the hinge (the corner of the hinge terminal at the rear end of the hinge surface is in a right angle state. In this way, when the distance between the hinge terminal and the L shape is small, the hinge terminal can only make a small angle swing on both sides with the hinge axis as the axis. Figure 4 (As shown in Figure c), the traction portion 51 can rotate or swing around the hinge axis with the outer arm 32. To control the angle of the traction portion 51, a second telescopic electric cylinder 50 is provided between the upper side of the traction portion 51 and the top of the outer arm 32. The second telescopic electric cylinder 50 controls the tilt angle of the traction portion 51, which facilitates adjustment of the traction position of the traction portion 50. The first support portion 52 is provided near the lower end of the outer arm, and the second support portion 53 is provided at the lower end of the inner arm 31. The first support portion 52 and the second support portion 53 each have a rear contact surface (521, 531) 521, with the front contact surface and the rear contact surface disposed opposite each other.

[0035] In some embodiments, first hinge terminals are provided on the opposing surfaces of the fixed arm 2 and the inner arm 31, and both ends of the first telescopic cylinder 4 are hingedly connected to the first hinge terminals. To prevent the hinge terminals from affecting the raising and lowering of the outer arm 32, a sliding hole 321 is provided on the outer arm 32. The first hinge terminal on the inner arm 31 is located within the sliding hole 321, so that when the movable arm 3 is extended or retracted, the first hinge terminal on the inner arm 31 slides relative to the sliding hole 321. A notch 322 is provided at the lower end of the outer arm 32, opposite the sliding hole 321. The second support portion 53 can enter or exit the notch 322 when the outer wall 32 descends or ascends.

[0036] In some embodiments, the first support part 52 and the second support part 53 both include an electric telescopic rod, and an arc-shaped end is fixedly provided at the far end of the electric telescopic rod. The end of the arc-shaped end away from the telescopic rod is an arc-shaped surface, and the arc-shaped surface contacts the outer side surface of the supporting tank body to apply tension or support force to the tank body.

[0037] A fixed support end 54 is also provided on the outer arm 32, opposite the front contact surface of the pulling portion 51. During use, the fixed support end 54 and the front contact surface 511 of the pulling portion 51 together clamp the top of the tank. The fixed support end has the same structure as the first or second support portion, and of course, the fixed support end can also be non-retractable.

[0038] Preferably, in the initial state, the distance between the arc surface of the first support part 52 and the movable arm 3 is smaller than the distance between the arc surface of the second support part 53 and the movable arm 3. This ensures that during the clamping process, the tank body is first clamped off the ground by the traction part 51 and the second support part 53. At the clamping point, the traction part 51 cooperates with the second support 53 so that the torque of the traction part 51 is larger.

[0039] Preferably, handles are provided on both sides of the fixed arm 2, by which the device can be pushed to move. At the same time, a control button is provided on the top of the fixed arm 2, and a battery is provided on the upper side of the base 1. The battery is electrically connected to each telescopic cylinder and the control button to control the movement of each telescopic cylinder through the hole button.

[0040] Finally, it should be noted that during transportation, the movable arm 3 is held by the fixed support end 54 , the first support portion 52 and the traction portion 51 .

[0041] It should be understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
