Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting devices, in particular to a sand box with a high-altitude anti-falling safety protection device. Background Art
[0002] Sand box molding is generally used for large castings. During molding, multiple layers of sand boxes are usually stacked to reach the required height. The height is generally high, usually more than 3 meters in total, and some even exceed 5 meters. The shapes of sand boxes include round boxes, square boxes and special-shaped boxes, and round boxes are generally more common.
[0003] Operators need to frequently work on the flat surface at the top of the sand box, generally moving along the outer edge of the sand box. However, existing sand boxes generally do not have protective measures. Even if operators wear anti-fall safety belts, there is nowhere to hang them, so there is a safety risk of falling from heights and getting injured.
[0004] In order to prevent workers from falling and injuring themselves when working at heights, it is particularly important to develop a sand box that is easy to operate and can be equipped with a safety belt. Summary of the invention
[0005] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide a sand box with a high-altitude anti-falling safety protection device.
[0006] The specific scheme of the utility model is: a sand box with a high-altitude anti-fall safety protection device, comprising a sand box body, a plurality of mounting seats are evenly distributed along the circumference of the outer upper end of the sand box body, the mounting seats are fixedly connected to the sand box, a plug hole is provided on the top of each mounting seat, a detachable support rod is installed in each plug hole, a hanging ring is provided on both sides of the top of the support rod, a support chain is installed between every two adjacent support rods, a hook is provided at each end of the support chain, the hook is used to be connected to the hanging ring, and the support chain is used to hang the safety hook of the anti-fall safety belt.
[0007] Furthermore, a sealing plate is provided at the bottom end of the jack.
[0008] Furthermore, the insertion hole is a through hole, and a limiting protrusion is provided in the middle of the support rod, and the limiting protrusion is used to limit the support rod when the support rod is inserted into the insertion hole of the mounting seat.
[0009] Furthermore, the mounting seat is fixed to the sand box body by welding.
[0010] Furthermore, the length of the support rod inserted into the insertion hole accounts for 1 / 10-1 / 5 of the total length of the support rod, and the gap between the support rod and the insertion hole is 1-3 mm.
[0011] Furthermore, the length of the support rod is 1.2-1.8m.
[0012] Compared with the prior art, the utility model has the following advantages: by providing a detachable support rod and a detachable support chain, the operator can hang the safety hook of the safety belt on the support chain, thereby solving the problem that the safety belt worn by the operator has no hanging point, and can effectively prevent the operator from falling when working on the edge of the sand box, avoiding accidents of falling and injury to people; the installation and disassembly of the support rod and the support chain are simple and easy to operate, and at the same time do not affect the normal operation of the operator.

[0019] Embodiment 1
[0020] See also Figure 1-4 The present embodiment is a sand box with a high-altitude anti-fall safety protection device, including a sand box body 1 with a diameter of 3 meters. The sand box body 1 is formed by stacking multiple sand boxes and has a height of about 3.5 meters. Six mounting seats 2 are evenly distributed along the circumference of the outer upper end of the sand box body 1. The top surface of the mounting seat 2 is 20 mm away from the top surface of the sand box. The mounting seat 2 is fixedly connected to the sand box. A socket with a diameter of 28 mm is provided on the top of each mounting seat 2. A detachable support rod 3 is installed in each socket. The diameter of the support rod 3 is 25 mm. A hanging ring 5 is provided on both sides of the top of the support rod 3. A support chain 4 is installed between each adjacent two support rods 3. A hook 6 is provided at each end of the support chain 4. The hook 6 is provided with an opening. The detachable connection of the support chain 4 is realized by connecting the hook 6 with the hanging ring 5. The support chain 4 is used to hang the safety hook 6 of the anti-fall safety belt.
[0021] Furthermore, a sealing plate is provided at the bottom end of the jack.
[0022] Furthermore, the mounting seat 2 is fixed to the flask body 1 by welding.
[0023] Furthermore, the length of the support rod 3 inserted into the insertion hole accounts for 1 / 10-1 / 5 of the total length of the support rod 3, and the gap between the support rod 3 and the insertion hole is 1-3 mm.
[0024] Furthermore, the length of the support rod 3 is 1.2-1.8m. When using this embodiment, the sand box with the mounting seat 2 is placed on the top layer of the stacked sand boxes, and then the six support rods 3 are inserted into the sockets of each mounting seat 2, and finally the six support chains 4 are installed on the top of the support rods 3; then the operator climbs onto the top surface of the sand box to perform the molding operation, and before the operation, the safety hook 6 of the safety belt is hung on the support chain 4, and when the operator moves, the safety belt can be moved to the nearest support chain 4 together, so as to ensure the safety of the operator during the entire molding operation.
[0025] After the operation is completed, the support rod 3 and the support chain 4 are removed for standby use.
[0026] Embodiment 2 The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 5 The socket is a through hole, and a limiting protrusion 31 is provided in the middle of the support rod 3. The limiting protrusion 31 is used to limit the support rod 3 and provide support when the support rod 3 is inserted into the socket of the mounting seat 2.
[0027] The limiting protrusion 31 is welded and fixed to the support rod 3 by a plurality of vertical ribs, and the bottoms of all the vertical ribs are plane and located at the same height. In this embodiment, the through hole is provided to prevent dust from accumulating on the socket, and the socket is convenient to clean.
