DETAILED DESCRIPTION

[0026] like Figure 1 and Figure 2 The figure shows a manually adjustable positioning seat of a slab clamp disclosed in the utility model, which comprises a positioning seat body 1, an adjustment seat 2, an adjustment mechanism 3 and an adjustment pin 4;

[0027] The positioning seat body 1 is provided with a hand wheel operating cavity 10;

[0028] The adjustment mechanism 3 includes a driving hand wheel 30 and a lead screw 31. The driving hand wheel 30 is located in the hand wheel operation cavity 10 and is mounted on the positioning seat body 1. The driving hand wheel 30 is provided with a driving thread that cooperates with the lead screw 31.

[0029] The lead screw 31 is installed on the positioning seat body 1 and the upper end is screwed with the driving thread. The lower end of the lead screw 31 is provided with the adjustment seat 2. The adjustment seat 2 is located at the lower end of the positioning seat body 1, and the adjustment seat 2 can be driven up and down by the driving hand wheel 30 and the lead screw 31 to adjust the distance between the adjustment seat 2 and the lower end of the positioning seat body 1.

[0030] Specifically, Figure 1 and Figure 2As shown, the positioning seat slab clamp includes a hanging beam 70, a clamp arm assembly 71 and a positioning seat body 1. A group of clamp arm assemblies 71 are respectively installed at both ends of the hanging beam 70. A clamp claw is provided at the lower end of the clamp arm assembly. The clamp arm assembly can be closed or opened and clamp or release the slab through the clamp claw. A positioning seat body 1 is also provided on the clamp arm assembly. When the positioning seat slab clamp is used to clamp the slab, after the lower end of the positioning seat body abuts against the upper end of the slab, the clamp arm assembly is closed to clamp the slab. The distance between the lower end of the positioning seat body and the clamp claw determines the thickness or number of the slab that the positioning seat slab clamp can clamp. In this application, since an adjustment seat and an adjustment seat are also provided, The adjusting seat is arranged at the lower end of the positioning seat body, and the adjusting mechanism can drive the adjusting seat to move up and down relative to the fixed seat body. Specifically, a lead screw is installed on the positioning seat body, and the upper end of the lead screw cooperates with a driving hand wheel installed on the positioning seat body. A driving thread is provided on the driving hand wheel, and the driving thread can be directly processed on the driving hand wheel, or a nut structure can be fixed on the driving hand wheel. The driving hand wheel drives the lead screw to move up and down through the driving thread structure, and the lower end of the lead screw is connected with the adjusting seat. In the process of the lead screw moving up and down, the adjusting seat also rises or falls with the lead screw, so that the distance between the lower end of the adjusting seat and the clamp claw can be adjusted. Figure 3 As shown, the adjusting seat is driven down by the lead screw and the driving hand wheel so that the vertical distance between the lower end surface of the adjusting seat and the clamping claw is reduced to h. At this time, the thickness of the slab that can be clamped by the positioning seat slab clamp is small, such as Figure 4 As shown, the adjusting seat is driven to rise by the lead screw and the driving hand wheel so that the vertical distance between the lower end surface of the adjusting seat and the clamping claw increases to H. At this time, the positioning seat slab clamp can clamp a larger slab thickness. When the positioning seat slab clamp disclosed in the present application clamps the slab, the lower end of the adjusting seat abuts against the slab, and then the clamp arm assembly closes to clamp the slab. Because the adjusting seat can move up and down under the drive of the lead screw and the driving handle to adjust the distance between the lower end of the adjusting seat and the clamping claw, the positioning seat slab clamp can lift slabs of different thicknesses or numbers of blocks within a certain range. At the same time, it has the advantages of simple structure, light weight, low failure rate and low manufacturing cost.

[0031] Furthermore, if Figure 5As shown, the adjustment seat 2 includes an adjustment seat bottom plate 20 and a plurality of adjustment seat side plates 21 arranged on the adjustment seat bottom plate 20, and the plurality of adjustment seat side plates 21 surround a positioning seat body receiving groove 22, and the adjustment seat 2 is buckled on the lower end of the positioning seat body 1 through the positioning seat body receiving groove 22. In this embodiment, the adjustment seat bottom plate 20 and the positioning seat body are square plate structures consistent with the shape of the lower end surface of the positioning seat body, and the four sides of the square plate are fixed with adjustment seat side plates 21, and the adjustment seat side plates 21 surround the positioning seat body receiving groove 22, and the adjustment seat can be buckled on the lower end of the positioning seat body 1. Since the adjustment seat includes an adjustment seat bottom plate and side plates, and the side plates surround a receiving groove structure, the adjustment seat is buckled on the positioning seat body, so that during the up and down movement of the adjustment seat, the receiving groove surrounded by the side plates can play a guiding role to prevent the adjustment seat from rotating integrally with the lead screw. At the same time, the adjustment seat can protect the positioning seat body. The adjustment seat of this structure not only has a simple structure, but also prolongs the service life of the positioning seat slab clamp.

[0032] Further, it also includes a safety pin 50;

[0033] The positioning seat body 1 is provided with a safety pin shaft hole 11 , and the safety pin shaft 50 can be inserted into the safety pin shaft hole 11 to lock the driving hand wheel 30 .

[0034] Specifically, in this embodiment, one or more safety pin holes 11 are provided on the positioning seat body in the handwheel operating cavity, and a transverse rib 33 is provided on the driving handwheel. When the driving handwheel drives the lead screw to move up and down to the set position, the safety pin 50 can be inserted into the safety pin hole 11. The safety pin 50 contacts the transverse rib on the driving handwheel to lock the driving handwheel, thereby blocking the rotation of the driving handwheel and preventing the movement of the lead screw, thereby ensuring that the position of the adjustment seat remains unchanged, thereby realizing the position locking of the adjustment seat, especially when the clamp is unloaded, it can prevent the adjustment seat from falling due to gravity.

[0035] Furthermore, one or more adjustment pins 4 are provided between each positioning seat body 1 and the adjustment seat 2; the adjustment pins 4 can be inserted into the gap between the adjustment seat 2 and the positioning seat body 1 when the adjustment seat 2 is away from the lower end of the positioning seat body 1.

[0036] Specifically, in this embodiment, an adjustment pin socket 23 is provided on the adjustment seat side plate 21, and the adjustment pin 4 can be inserted into the gap between the adjustment seat 2 and the positioning seat body 1 through the adjustment pin socket 23. The setting of the adjustment pin avoids the damage to the lead screw caused by the deadweight load and impact load when the positioning seat slab clamp is close to the slab. At the same time, the thickness of the pin accurately controls the required adjustment distance. In this application, different distance requirements can be met by inserting pins of different thicknesses, or by stacking multiple pins to meet different distance requirements.

[0037] Furthermore, if Figure 6 As shown, the adjustment pin 4 includes an adjustment pin body 40 that can be inserted between the positioning seat body 1 and the adjustment seat 2 and an adjustment pin handle 41 disposed on one side of the adjustment pin body 40. In this embodiment, the adjustment pin is an "L"-shaped plate structure, the longer side of which is the adjustment pin body, and the shorter side is the adjustment pin handle. The adjustment pin body can be inserted between the bottom plate of the adjustment seat and the bottom surface of the positioning seat body to avoid damage to the lead screw caused by the deadweight load and impact load when the positioning seat slab clamp is close to the slab. The adjustment pin handle can facilitate the operator to insert or pull out the adjustment pin into the gap between the adjustment seat and the positioning seat body.

[0038] Furthermore, a limit pin hole 42 is provided on the adjustment pin 4 and the adjustment seat 2. When the adjustment pin 4 is inserted between the adjustment seat 2 and the positioning seat body 1, a limit pin 6 for locking the adjustment seat 2 and the adjustment pin 4 can be inserted into the limit pin hole 42.

[0039] Specifically, in this embodiment, both the adjustment pin body and the adjustment seat bottom plate are provided with a limit pin hole 42. After the adjustment pin body is inserted between the adjustment seat and the positioning seat body, the limit pin can be simultaneously inserted into the limit pin holes on the adjustment pin body and the adjustment seat bottom plate, thereby locking the adjustment pin and the adjustment seat, thereby avoiding the movement of the adjustment pin and ensuring the safety of the construction process. In this embodiment, the height of the adjustment pin socket 23 on the adjustment seat side plate 21 is greater than the thickness of the adjustment pin body, so that in the process of inserting the adjustment pin, the adjustment seat can be lowered by the screw and the driving hand wheel to a distance greater than the required height (the thickness of the adjustment pin) so that the adjustment pin can be inserted between the adjustment seat and the positioning seat body, and at the same time, a limit pin can be inserted into the adjustment pin socket to achieve the locking of the adjustment pin and the adjustment plate, and then, the adjustment seat is adjusted to the desired position (that is, the distance between the lower end of the positioning seat body and the adjustment seat is consistent with the thickness of the adjustment pin) by the screw and the driving hand wheel. At this time, the positioning seat slab clamp can clamp slabs with smaller thickness or fewer quantities; and when the positioning seat is required When the slab clamp is able to clamp slabs of larger thickness or larger quantity, the adjusting seat is first lowered a certain distance by means of the lead screw and the driving hand wheel so that the adjusting pin can be lifted between the positioning seat body and the adjusting seat, and then, the limit pin is lifted together with the adjusting pin and separated from the limit pin hole on the adjusting seat. At this time, the adjusting pin can be pulled out from between the positioning seat body and the adjusting seat, and then, the adjusting seat is raised to the required position (generally, the lower end surface of the positioning seat body is in contact with the bottom plate of the adjusting seat) by means of the lead screw and the driving hand wheel; the limit pin can also be installed on the positioning seat body, and when the adjusting pin is inserted into or removed from the adjusting seat, the limit pin is fixed on the positioning seat body, and the limit pin hole of the adjusting pin is sleeved on the limit pin or separated from the limit pin.

[0040] Furthermore, it also includes a fixed safety cover 32 arranged at the upper end of the lead screw 31 to prevent the lead screw from being separated from the driving hand wheel due to excessive descent.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
