A cylinder lifting clamp, the structure of which can be illustrated in figures 1 and 4, the apparatus comprising: a first clamp 1, a second clamp 2 and a tray 3. First holder 1 and second holder 2 staggered arrangement all are equipped with link 6 in the bottom of two holders, tray 3 sets up the below at two holders. Optionally, the hanging ring 6 and the clamping piece are of a detachable connection structure, specifically, a bolt hole is formed in the bottom of the clamping piece, and a connection bolt is arranged on the hanging ring 6. When the device works, a worker can insert the connecting bolt into the bolt hole, so that the hanging ring 6 and the connecting piece are assembled. Tray 3 links to each other with two link 6 respectively through hoist cable 4, can carry out the bearing to the bottom of steel bottle through tray 3, when hoisting the steel bottle through this device, the gravity of steel bottle self can make 3 downstream of tray, and this motion is ordered about and can be transmitted to link 6 through hoist cable 4 on. Because two links 6 all set up the bottom at the holder, consequently first holder 1 and second holder 2 will use the staggered point to rotate as the axle, and this rotation process will make the contained angle between two holders diminish to the realization is fixed to the centre gripping of steel bottle lateral wall.
Optionally, in order to facilitate the hoisting of the device, a first ear loop 51 and a second ear loop 52 are further provided inside the device. The first ear loop 51 is arranged on the first holder 1 and the second ear loop 52 is arranged on the second holder 2. Illustratively, the earring may be connected to the holder by welding. When hoisting, two earrings link to each other through connecting cable 53, can carry this device on hoisting accessory's lifting hook through connecting cable 53, make things convenient for hoisting accessory to transport the steel bottle.
In addition, for avoiding the hoisting position to cause the influence to the clamping effect of this device, the earrings should set up the top position department at the holder.
Fig. 2 is a schematic structural diagram of the first clamping member 1, and fig. 3 is a schematic structural diagram of the second clamping member 2, as shown in the drawings, the first clamping member 1 is provided with a first clamping portion 11 and a second clamping portion 12, and the second clamping member 2 is provided with a third clamping portion 21 and a fourth clamping portion 22. A first clamping gap is formed between the first clamping part 11 and the third clamping part 21, a second clamping gap is formed between the second clamping part 12 and the fourth clamping part 22, and the first clamping gap and the second clamping gap are respectively positioned at two sides of the staggered point. At the during operation, for promoting the stability of steel bottle centre gripping, can make the staggered point of two holders coincide mutually with the mid point of steel bottle, first centre gripping clearance can carry out the centre gripping to the first half of body fixed this moment, and second centre gripping clearance can carry out the centre gripping to the latter half of body fixed, consequently enables this device and obtains the fixed effect of firm centre gripping more stably.
Optionally, in this embodiment, the first clamping member 1 and the second clamping member 23 are both waist-shaped rings, and the arc-shaped section of each waist-shaped ring is the clamping portion in this embodiment. When this device carries out the during operation, treat that the steel bottle of centre gripping arranges the inside of waist type ring in, the arc part in the ring will carry out the centre gripping to the lateral wall of steel bottle, avoids the steel bottle to take place to rock at the in-process that lifts by crane. In addition, to ensure that the inner walls of the two rings are simultaneously in contact with the cylinder side wall, the minimum inner diameters of the first and second clamps 1, 2 should be kept equal.
For the convenience two staggered arrangement's holder rotates, first holder 1 includes the first groove 13 of dodging, first groove 13 of dodging is total two, and the relative arrangement is on the inner wall of first holder 1. Correspondingly, a second avoidance groove 23 matched with the first avoidance groove 13 is formed in the second clamping piece 2, and the second avoidance groove 23 is formed in the outer wall of the second clamping piece 2. When the two clamping pieces are combined into a whole, the first avoidance groove 13 and the second avoidance groove 23 are aligned, and the avoidance grooves can provide a moving space for the rotation of the two clamping pieces, so that the clamping pieces are prevented from interfering with each other when the opening and closing angle is adjusted.
In addition, the avoidance groove is arranged to enable the staggered point between the first clamping piece 1 and the second clamping piece 2 to have the function of automatic adjustment. When the bottom surface of the steel cylinder is dislocated with the center of the tray, the two clamping pieces slightly move in the hoisting process, the relative position between the first avoidance groove 13 and the second avoidance groove 23 can be changed by the movement, and therefore the staggered point of the two clamping pieces moves and finally moves on the axis of the steel cylinder. The mechanical stability of this device when hoist and mount steel bottle can be promoted through the automatically regulated function of staggered point, avoids the steel bottle to take place the landing because of the deviation of placing the position.
Because second holder 2 sets up inside first holder 1, consequently two will form the installation passageway between the first groove 13 of dodging, through the installation passageway enables inside second holder 2 inserts first holder 1, makes two holders be the wrong gesture and arranges. In addition, for facilitating the two clamping pieces to be disassembled and improving the portability of the device, the maximum passing inner diameter of the installation channel is larger than the outer diameter of the second clamping piece 2, and the minimum passing inner diameter is smaller than the outer diameter of the second clamping piece 2. For example, as shown in fig. 2, the first avoiding groove 13 may be a rectangular groove, and a mounting passage having a rectangular cross section may be formed by the two rectangular grooves. At the moment, the maximum passing inner diameter in the channel is the length of a diagonal line of the rectangle, and the minimum passing inner diameter is the distance between the bottoms of the two rectangle grooves. When the installation is carried out, a worker can align the second clamping piece 2 with the diagonal line of the rectangle, and the passing inner diameter of the installation channel is larger than the outer diameter of the second clamping piece 2, so that the second clamping piece 2 can be smoothly inserted into the installation channel; when the second avoiding groove 23 is opposite to the first avoiding groove 13, the bottom surface of the second avoiding groove 23 is opposite to the bottom surface of the first avoiding groove 13 through rotation of a worker, and under the posture, the outer diameter of the second clamping piece 2 is smaller than the passing inner diameter of the installation channel, so that the second clamping piece 2 and the first clamping piece 1 can form a whole which is not easy to separate. After the hoisting work, the staff accessible rotates and makes second holder 2 align with the diagonal of installation passageway again to make second holder 2 and first holder 1 separation. Through the separation of two holders, can make things convenient for the staff to carry and keep this device, avoid the holder to take place to warp under long-term staggered state simultaneously.
Correspondingly, the edge portions of the first avoiding groove 13 and the second avoiding groove 23 should be provided with chamfers to facilitate the rotation of the second clamping member 2 by the worker.
In addition, as an optional implementation manner of this embodiment, the crossing point of the two clamping members may be located at the center of the clamping member, or may be offset from the center of the clamping member. When the staggered point is positioned at the central position of the clamping piece, the distances from the first clamping gap and the second clamping gap to the staggered point are equal, so that the opening angles of the first clamping gap and the second clamping gap are the same, and the device can be used for clamping conventional steel cylinders with constant diameters, such as oxygen cylinders. When the staggered point deviates from the center of the clamping piece, such as being close to the top of the clamping piece, the distance from the first clamping gap to the staggered point is less than the distance from the second clamping gap to the staggered point, so that the opening angle of the first clamping gap is less than that of the second clamping gap, and the device can be used for clamping the reducing steel cylinder. In actual working conditions, the steel cylinder to be clamped may have a local diameter-changing condition, such as a common gas cylinder, a portable section with a smaller diameter is arranged at the top of the gas cylinder, and an accommodating section with a larger diameter is arranged in the middle of the gas cylinder. When carrying out the centre gripping to such steel bottle, accessible adjustment staggered point's position makes first centre gripping clearance be less than second centre gripping clearance to carry out the centre gripping to portable section through first centre gripping clearance, the second centre gripping clearance is held the section of holding. This device will lift and the centre gripping bottom, middle part (holding section) and top (portable section) to the gas tank this moment for the gas tank can be more reliable and stable lift by crane.
In addition, in order to facilitate the alignment of the staggered point of the two clamping members with the center of the clamping members, the lengths of the first avoidance groove 13 and the second avoidance groove 23 should be equal, the midpoint of the first avoidance groove 13 coincides with the midpoint of the first clamping member 1, and the midpoint of the second avoidance groove 23 coincides with the midpoint of the second clamping member 2.
Optionally, for promoting the frictional resistance between clamping part and the steel bottle, avoid the steel bottle to appear sliding when hoist and mount, this device is still including arc blotter 7, arc blotter 7 detachable sets up on the inboard lateral wall of first clamping part 11, second clamping part 12, third clamping part 21 and fourth clamping part 22. Specifically, the arc-shaped cushion pad 7 is provided with a mounting bolt, and the clamping portion is provided with a bolt hole matched with the mounting bolt. When this device carries out steel bottle centre gripping during operation, the staff can install arc blotter 7 on the clamping part, promotes the frictional resistance between this device and the steel bottle. After the arc-shaped buffer cushion 7 is aged, the worker can detach the arc-shaped buffer cushion 7 and replace the arc-shaped buffer cushion in time.
Illustratively, the arc cushion 7 of the present embodiment may be made of a rubber material.
In addition, because first holder 1 and second holder 2 need open and shut the adjustment of angle when using, consequently the staff need frequent the position to the staggered point and the angle of two holders is adjusted, for avoiding the staff to be hindered by the holder clamp in the adjustment process, can set up on first holder 1 or second holder 2 and prevent that clamp bolt 8. As shown in fig. 4, in the present embodiment, the anti-pinch bolt 8 is disposed on the first clamping member 1, and the anti-pinch bolt 8 is perpendicular to the plane of the first clamping member 1. When the staff carries out the angle modulation to the holder, can earlier with preventing that clamp bolt 8 screws out certain length, utilize and prevent that clamp bolt 8 restricts the minimum angle that opens and shuts of two holders, prevent to cause the injury to the staff.
The working process of the above scheme is explained as follows:
before the work is carried out, the arc-shaped buffer pad 7 is installed on the clamping pieces, and then the installation channel inserts the second clamping piece 2 into the first clamping piece 1, so that the assembly of the two clamping pieces is completed.
The tray 3 is then connected to the clamps by slings 4 and the cylinders are placed on the tray 3. Then, the screwing-out length of the anti-pinch bolt 8 is adjusted, and the opening angle of the two clamping pieces is adjusted according to the specification of the steel cylinder. Subsequently, the clamping piece is connected with the hoisting device through the connecting cable 53, and the steel cylinder is hoisted and transported by the hoisting device.
After the hoisting work is finished, the two clamping pieces are separated by rotating the second clamping piece 2, and the accessories are correspondingly disassembled.
The following explains the effects of the above scheme:
this embodiment provides a steel bottle stone tongs, can carry out centre gripping hoist and mount to the steel bottle of different specifications, consequently can promote the efficiency of steel bottle transport. Secondly, this device can lift simultaneously and the centre gripping bottom, first half and the latter half of steel bottle, and consequently the stability of centre gripping is higher, and the steel bottle is difficult for taking place to rock or drop when hoist and mount. In addition, first holder 1 and second holder 2 can assemble or dismantle according to the work needs in this device, have promoted stone tongs's portability.
