[0032] The protection bin 1 is fixed at the reserved hole through the protection mechanism, so that the construction personnel or the construction waste is prevented from falling into the reserved hole, the protection effect is achieved, the practicality is better, and the construction reserved hole protection device is more convenient to use and popularize.

[0033] In the embodiment, the protection bin 1 and the mounting bin 201 are circular bins, the connecting plate 203 is a circular plate, and the mounting bin 201, the protection bin 1 and the connecting plate 203 are located on the same central axis, and the protection bin 1 is fixed with anti-skid handrails on the left and right sides.

[0034] Please refer to Figure 1 In the embodiment, the protection mechanism further comprises a pneumatic cylinder 208 fixed on the top surface of the protection bin 1, a lifting plate 209 fixed on the bottom end of the output shaft of the pneumatic cylinder 208, four support rods 210 fixed on the bottom surface of the lifting plate 209 and universal wheels 211 arranged on the bottom end of the support rods 210, when it is needed to move the protection bin 1, the motor 202 is controlled to reverse, and then the pneumatic cylinder 208 is started to contract, the pneumatic cylinder 208 drives the lifting plate 209 to move downward in the protection bin 1, so that the support rods 210 penetrate through the protection bin 1 and the universal wheels 211 at the bottom end thereof contact the ground, the protection bin 1 is lifted up, the protection bin 1 is supported through the support rods 210, and the protection bin 1 is moved through the universal wheels 211.

[0035] It should be noted that the control mode of the present application is controlled by the controller, and the control circuit of the controller can be realized by simple programming of those skilled in the art, and the power supply also belongs to the common knowledge in the art, and the present application is mainly used to protect the mechanical device, so the control mode and circuit connection will not be explained in detail.

[0036] In the embodiment, the lifting plate 209 is a circular plate, the top surface of the protective bin 1 is provided with a movable hole for the output shaft of the air cylinder 208 to penetrate, and the bottom surface of the protective bin 1 is provided with four sliding holes for the supporting rods 210 to penetrate.

[0037] Please refer to Figure 1 With Figure 3 In the embodiment, the auxiliary mechanism includes a rectangular bin 301 fixed on the left side of the protective bin 1, a guide rod 302 slidingly connected to the bottom surface of the rectangular bin 301, a first contact block 303 fixed on the top end of the guide rod 302, a spring 304 fixed on the inner top wall of the rectangular bin 301, a second contact block 305 fixed on the bottom end of the spring 304, and an alarm 308 installed on the top surface of the protective bin 1. When the protective bin 1 is used to protect the reserved hole, the bottom surface of the protective bin 1 is in contact with the ground, at this time, the bottom end of the guide rod 302 is in contact with the ground, thereby pushing the first contact block 303 to move upward and contact the second contact block 305. The first contact block 303 and the second contact block 305 are connected by wires to the circuit of the alarm 308. When the first contact block 303 and the second contact block 305 are in contact, the alarm 308 is short-circuited to make it not work. When the reserved hole needs to be used and the protective bin 1 is moved, the protective bin 1 will move upward, so that the first contact block 303 moves downward under the action of gravity, and then separates from the second contact block 305. At this time, the first contact block 303 and the second contact block 305 no longer short-circuit the alarm 308, so that the alarm 308 normally connects to the circuit to work and alarm to remind the surrounding staff to pay attention to safety.

[0038] In the embodiment, the first contact block 303 and the second contact block 305 are opposite to each other, and the first contact block 303 and the second contact block 305 are both metal conductive blocks. It should be noted that a protection resistor should be provided in the circuit of the alarm 308 to avoid connecting the positive and negative poles of the power supply directly through the wires when the alarm 308 is short-circuited. This kind of short-circuiting circuit is a mature and disclosed technology in the prior art, therefore, the specific structure thereof will not be described in detail.

[0039] Please refer to Figure 3In the embodiment, the left and right sides of the first contact block 303 are fixed with guide blocks 306, the left and right inner walls of the rectangular bin 301 are provided with guide grooves 307 for sliding connection of the guide blocks 306, and the bottom surface of the rectangular bin 301 is provided with a guide hole for penetration of the guide rod 302 and sliding movement of the guide rod 302 in the guide hole. The cooperation of the guide blocks 306 and the guide grooves 307 facilitates the stability of the lifting guide rod 302 for driving the first contact block 303 to move up and down, and thus facilitates the contact between the first contact block 303 and the second contact block 305.

[0040] The working principle of the above embodiment is as follows:

[0041] (1) In use, the protective bin 1 is placed on the top of the reserved hole, the mounting bin 201 is inserted into the reserved hole, and then the motor 202 is started. The motor 202 drives the connecting plate 203 to rotate, the connecting plate 203 drives the end of the plurality of hinged rods 204 close to the connecting plate 203 to revolve around the central axis of the output shaft of the motor 202, and thus the end of the hinged rod 204 away from the connecting plate 203 pushes the turnover rod 205 to turn inside the accommodating hole 207, so that the turnover plate 206 at the end of the plurality of turnover rods 205 can contact and support the inner wall of the reserved hole, achieving the effect of fixing the protective bin 1. When it is necessary to move the protective bin 1, the motor 202 is first controlled to reverse, and then the air cylinder 208 is started to contract. The air cylinder 208 drives the lifting plate 209 to move downward inside the protective bin 1, and thus the supporting rod 210 penetrates the protective bin 1 and the universal wheel 211 at the bottom end of the supporting rod 210 contacts the ground, simultaneously lifting the protective bin 1 by the supporting rod 210 and moving the protective bin 1 by the universal wheel 211;

[0042] (2) When the protective bin 1 is used to protect the reserved hole, the bottom surface of the protective bin 1 contacts the ground, at this time the bottom end of the guide rod 302 contacts the ground, and thus the first contact block 303 is pushed to move upward and contact the second contact block 305. The first contact block 303 and the second contact block 305 are connected by wires to the circuit of the alarm 308. When the first contact block 303 and the second contact block 305 are in contact, the alarm 308 is short-circuited and does not work. When it is necessary to use the reserved hole and move the protective bin 1, the protective bin 1 moves upward, so that the first contact block 303 moves downward under the action of gravity and thus separates from the second contact block 305. At this time, the first contact block 303 and the second contact block 305 no longer short-circuit the alarm 308, so that the alarm 308 is normally connected to the circuit and works to alarm and alert the surrounding staff to pay attention to safety.
