Description

Technical Field

[0001] The invention relates to the technical field of clamping, in particular to a novel brick clamping device. Background Art

[0002] Clamping devices are used in all walks of life. Among the bricks produced by brick factories, the fired bricks need to be stacked or loaded and unloaded. In the process of loading and unloading and stacking, it is not possible to fully realize automatic loading and unloading and stacking. In particular, in order to meet the needs of flexible transportation, manual loading and unloading are still required. The brick clamping device currently used is commonly known as a "brick clamp". It uses two broken iron rods connected together by the principle of a lever. It mainly relies on human clamping. When clamping bricks, people need to always maintain a very high grip for support, which is very physically demanding. When clamping bricks, people need to maintain a very high grip for support, which is very physically demanding. When holding a certain number of bricks, the gripping strength is greatly consumed, and the bricks will frequently fall during the clamping and lifting process. In order to avoid this situation, people are constantly updating the structure and shape of the brick clamp to enable people to exert more force, but it still requires people's gripping strength. The general brick clamp will greatly consume the gripping strength of people's hands when in use. The gripping strength will be weakened after clamping the bricks for a long time, and the bricks will fall. At the least, the bricks will be broken, and at worst, the workers will be injured. There are certain safety hazards, so a new brick clamping device is needed. Summary of the invention

The hand does not touch the internal clamping structure when gripping, and is not easily pinched. An elastic slide is fixedly connected to the inner bottom wall of the rubber protective cover, and the elastic slide allows two clamping rods to be operated at the same time. The surface of the elastic slide is arc-shaped, and the material of the elastic slide is spring steel. A push spring is fixedly connected to the surface of the elastic slide, and the top of the push spring is fixedly connected to the inner wall of the adjusting slot, and the push spring can cause the two clamping rods to expand.

[0007] In order to enhance the correlation between the two clamping rods, a preferred solution is that an elastic connecting strip is fixedly connected between the two clamping rods, and the surface of the elastic connecting strip is fixedly connected to the surface of the push spring. The elastic connecting strip can make the two clamping rods expand and contract synchronously.

[0008] In order to clamp and fix the bricks, a preferred solution is that the brick clamping mechanism also includes a triangular plate, an extension plate, an arc plate and a butt plate, the bottom of the clamping rod is fixedly connected to the triangular plate, the bottom end of the triangular plate is sharp, and the triangular plate can be quickly inserted into the brick, the surface of the clamping rod is fixedly connected to the extension plate, the extension plate can expand the supporting surface of the butt plate, the surface of the extension plate is fixedly connected to the surface of the triangular plate, the surface of the clamping rod is slidably connected to the butt plate, the surface of the clamping rod is provided with a slide groove, and the inner wall of the slide groove is slidably connected There is a telescopic rod, which can meet the extension needs of the support plate.

The surface of the arc plate is slidably connected to the surface of the clamping rod. The inner side surface of the support plate and the inner side surface of the arc plate are both arc-shaped. The thickness of the support plate tends to gradually become thicker from bottom to top, and the outer side surface of the support plate is a rectangle parallel to the extension plate. The surface of the support plate is rough, and the surface of the clamping rod is fixedly connected to a support rod, which is located on the inner side of the arc plate and the support plate.

[0009] In order to prevent bricks from falling, a preferred solution is that the locking and load-reducing mechanism includes an arc groove, and the inside of the two elbow rods are provided with an arc groove, and the inner wall of the arc groove is slidably connected with an arc pad, and the thickness of the arc pad gradually decreases from top to bottom, and the arc pad can squeeze the card plate so that the card plate is squeezed and propped up, and the surface of the arc pad is fixedly connected with a strong tension spring, and one end of the strong tension spring is fixedly connected to the inner wall of the arc groove, and the surface of each arc pad is hinged with a group of card plates, and the number of the card plates is the same as the number of adjusting screw holes, and the card plate passes through the elbow rod and extends to the outside of the elbow rod, and the surface of the clamping rod is fixedly connected with a plurality of groups of teeth, each group of teeth corresponds to a card plate, and the clamping rod has a tendency to rotate when expanding, and the teeth limit the rotation of the card plate, hold the card plate, and then jam the clamping rod.

[0011] (1) The present invention provides a brick clamping mechanism, wherein the adjusting bolts and adjusting screw holes can adjust the clamping range and the clamping angle according to individual circumstances. The triangle plate can be directly inserted into the middle of the brick to clamp the brick, and the elastic slide plate can clamp the brick with two clamping rods at the same time.

[0012] (2) The present invention provides a locking and load-reducing mechanism, which can lock the clamping plate with the help of the brick's own weight when clamping bricks, thereby limiting the expansion of the clamping plate and reducing the use of gripping force. Even if there is no grip, the brick can be prevented from falling, thereby greatly saving manpower and reducing safety hazards.

[0013] (3) The present invention provides structures such as abutment plates and abutment rods. When clamping bricks, as the bricks sink under their own weight, the abutment plates will press against the abutment rods, thereby reducing the gaps between the clamped bricks. This not only increases the friction between the bricks, but also quickly locks the clamping plate and the clamping teeth, thereby preventing the clamping rod from further expanding.

[0014] (4) In view of the problems of existing brick clamping devices that consume a lot of gripping force and bricks are prone to falling, the present invention designs a special structure that can use the weight of bricks to quickly clamp the clamping structure, thereby effectively solving the problem that ordinary brick clamps will greatly consume people's hand gripping force when in use, and the gripping force will be weakened after long-term brick clamping, and bricks will fall, which may break the bricks at the least and injure workers at the worst, posing certain safety hazards.

At this time, the plate 313 further reduces the gap between the bricks through the push rod 315, thereby increasing the friction of the bricks and increasing the outward force of the clamping rod 33. At this time, the latch tooth 45 presses and blocks the clamping plate 44. When the brick moves to the appropriate position, only when you let go of your hand, the strong tension spring 43 will drive the arc pad 42 to rebound, and the clamping plate 44 will be separated from the latch tooth 45. At this time, the clamping rod 33 is released.
