[0016] In order to make the purposes, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings, but the embodiments described in the present application are only some of the embodiments of the present application, rather than all the embodiments.

[0017] An embodiment of the present application provides a cylinder lifting appliance, as shown in FIG. Figures 1-5 The two ends of the length direction of the top plate 1 are both downwardly and transversely provided with transverse grooves 11, and the transverse grooves 11 are parallel to the width direction of the top plate 1.

[0018] The two ends of the length direction of the top plate 1 are symmetrically provided with two groups of clamping assemblies 2, the clamping assembly 2 comprises two symmetrically arranged triangular blocks 21, and the two triangular blocks 21 are arranged to be relatively moved along the width direction of the top plate 1, the top surface and the outer side surface corresponding to the two straight edges of the triangular block 21 are respectively parallel to the width direction and the height direction of the top plate 1, the inner side surface corresponding to the inclined edge of the triangular block 21 is arranged to be inwardly directed, the inner side surface of the triangular block 21 is open, the outer side surface of the triangular block 21 is vertically and transversely provided with a vertical groove 211, a vertical rod 212 is vertically arranged in the vertical groove 211, a sliding plate 22 is vertically and movably arranged on the vertical rod 212, a first spring 213 is sleeved on the vertical rod 212, and the first spring 213 is arranged above the sliding plate 22.

[0019] The side of the sliding plate 22 inside the triangular block 21 extends downwardly to form a downward extending plate 23, the bottom of the downward extending plate 23 vertically and inwardly extends to form a supporting plate 24, and the top surface of the end of the supporting plate 24 is a wedge surface.

[0020] The sliding plate 22 extends upward on one side outside the triangular blocks 21 to form an upper extension plate 25. The upper extension plates 25 of the two triangular blocks 21 on the same side in the length direction penetrate the transverse slots 11 on the corresponding side respectively and are connected by a connecting rod 26. The top of the connecting rod 26 is connected by a lifting rope 3, and the middle of the lifting rope 3 is provided with a lifting ring 4. When the lifting ring 4 moves upward under the connection of the lifting device, the force direction of the lifting rope 3 applied to the connecting rod 26 is symmetrical and consistent in size, thereby improving the synchronization of the movement of the two connecting rods 26.

[0021] In application, the cylinder is located on a placement plane. Through the relative movement of the two connecting rods 26, the two groups of upper extension plates 25 connected thereto are correspondingly moved to the two ends of the transverse slot 11. Under the action of the first spring 213, the sliding plate 22 is located at the bottom end of the vertical rod 212. At this time, the first spring 213 is in a natural state or a compressed state. At this time, the clamping assembly 2 is in an initial state, that is, the distance between the two triangular blocks 21 is a predetermined maximum value, and the distance between the support plate 24 and the top end of the triangular block 21 is a predetermined maximum value. When the lifting device is placed from above the cylinder, the distance between the two triangular blocks 21 and the distance between the support plate 24 and the top end of the triangular block 21 can adapt to the diameter of the cylinder, thereby realizing that the four triangular blocks 21 can be arranged on both sides of the cylinder respectively, and there is still a predetermined distance between the end of the support plate 24 and the cylinder.

[0022] Then, through the relative movement of the two connecting rods 26, the two groups of upper extension plates 25 connected thereto are correspondingly moved inward, thereby driving the corresponding support plates 24 of the triangular blocks 21 on both sides of the cylinder to also move inward. The wedge surface at the end of the support plate 24 simultaneously lifts the cylinder from both sides, until the two ends of the cylinder are supported by the support plates 24 and no longer contact the previous placement plane.

[0023] Finally, the lifting device is connected with the lifting ring 4, and the lifting device is used to lift the lifting device. Under the connection of the lifting rope 3, the two connecting rods 26 also move upward synchronously. The movement of the connecting rod 26 drives the upper extension plate 25 to also move upward. The movement of the upper extension plate 25 drives the sliding plate 22 to also move upward. The first spring 213 is in a compressed or continuously compressed state. The movement of the sliding plate 22 drives the lower extension plate 23 and the support plate 24 connected thereto to also move upward. Until the two clamping assemblies 2 clamp the two ends of the cylinder, that is, the inner side surfaces corresponding to the two triangular blocks 21 in the same clamping assembly 2 and the top surfaces of the two support plates 24 all abut against the outer side surface of the cylinder. At this time, the lifting device is used to continue lifting the lifting device. There will be no mutual movement between the connecting rod 26 and the top plate 1, that is, at this time, the lifting device will move upward as a whole.

[0024] Specifically, as Figure 4As shown, the ends of the support plates 24 are arranged on the inner side of the triangular blocks 21 to improve the support capacity of the support plates 24, that is, when the two triangular blocks 21 in the same set of clamping assemblies 2 are relatively moved towards the inner side, the two support plates 24 can be docked earlier to avoid the situation that the cylinder barrel is dropped due to the insufficient support capacity of the support plates 24.

[0025] Specifically, as shown in Figures 1-3 As shown, one of the support plates 24 in the same clamping assembly 2 has multiple first grooves arranged along the width direction of the top plate 1 at the ends thereof, and the other support plate 24 has second grooves staggered with the first grooves, which are used to form protrusions to cooperate with the first grooves of the one support plate 24, so as to expand the support range of the support plates 24 and improve the clamping stability of the clamping assembly 2, that is, when the two triangular blocks 21 in the same set of clamping assemblies 2 are relatively moved towards the inner side, the situation that the two triangular blocks 21 cannot continue to be relatively moved due to the interference between the ends of the support plates 24 during the process is avoided.

[0026] Specifically, as shown in Figures 3-5 As shown, there is a predetermined distance between the inner side of the upper extension plate 25 and the outer side of the triangular block 21, and the outer side of the triangular block 21 is provided with a sliding groove 27 along the length direction of the top plate 1, a U-shaped plate 5 is movably arranged in the sliding groove 27, the opening of the U-shaped plate 5 is arranged towards the sliding plate 22, the U-shaped plate 5 is used to limit the sliding plate 22 when the sliding plate 22 moves to a predetermined lowest point, and a second spring 271 is connected between the inner wall of the side of the sliding groove 27 away from the sliding plate 22 and the U-shaped plate 5. When the U-shaped plate 5 is used to limit the sliding plate 22, the second spring 271 is in a natural state or a compressed state. In actual use, before the lifting device is used to lift the lifting tool, the corresponding U-shaped plate 5 on the four triangular blocks 21 is moved away from the sliding plate 22, and when the U-shaped plate 5 no longer limits the sliding plate 22, the lifting tool can be lifted by the lifting device, and the sliding plate 22 will also move upwards along the vertical rod 212 in this process, releasing the U-shaped plate 5, and the U-shaped plate 5 will move towards the sliding plate 22 under the action of the second spring 271 until the second spring 271 is in a natural state.

[0027] Specifically, as shown in Figure 1 and Figure 2As shown, the two ends of the top plate 1 in the length direction are provided with guide rods 12 parallel to the width direction of the top plate 1, the guide rods 12 are rotationally connected below the top plate 1, two triangular blocks 21 are symmetrically arranged at the two ends of the guide rods 12, the two ends of the guide rods 12 are both sleeved with third springs 13, and the third springs 13 are arranged outside the triangular blocks 21. In actual use, when the lifting appliance is lowered from above the cylinder barrel, the two connecting rods 26 are first limited to drive the corresponding upper extension plates 25 connected thereto to move to the two ends of the transverse groove 11 respectively, so as to realize the placement of the lifting appliance. After the placement is completed, the limitation on the two connecting rods 26 is cancelled, and the triangular blocks 21 in the same group of clamping assemblies 2 are synchronously moved to the inside relative to each other under the action of the third springs 13 until the inner side surface of the triangular block 21 abuts against the outer wall of the cylinder barrel, and the third spring 13 is always in a compressed state. And when the lifting appliance is lifted by the lifting device, the force applied by the lifting rope 3 to the two connecting rods 26 can be decomposed into a vertical force and a horizontal force, the vertical force is embodied as the vertical upward movement of the connecting rod 26, and the horizontal force is embodied as the inward movement of the connecting rod 26, that is, the triangular block 21 will not only move inward under the action of the third spring 13, but also move inward under the driving of the connecting rod 26, preventing the triangular block 21 from shaking during lifting, thereby improving the stability of the clamping assembly 2 when clamping the cylinder barrel.

[0028] Specifically, as shown in the drawings, Figures 1-3 The side of the connecting rod 26 facing the outside is provided with a pull rod 28, so that the movement of the two connecting rods 26 can be more conveniently controlled when the lifting appliance is placed.

[0029] In application, the above only describes the preferred embodiments of the present application, and is not used to limit the present application. Obviously, those skilled in the art can make various modifications and changes to the present application without departing from the spirit and scope of the present application.
