DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The present application embodiment discloses a mobile device capable of fastening a safety belt for indoor high-altitude operations, which comprises: The support frame 1 is provided in two pieces and is used for bearing, and it can be a frame structure or a plate structure, such as a whole steel plate; The upper supporting mechanism 11 and the lower supporting mechanism 12 are respectively installed on the two supporting frames 1, and they can be moved and locked on the top surface and the ground of the building respectively; The middle support mechanism 2 is used to connect the two support frames 1 and adjust the distance between them; The cross bar 3 is rotatably mounted on the middle support mechanism 2, and one end of the two ends is a distal end and the other end is a proximal end. The distal end of the cross bar 3 is provided with a safety rope hanging point 31; The clamping rods 4 are provided with two and are arranged at both ends of the middle supporting mechanism 2; The follow-up traction mechanism is provided with two and is arranged one-to-one with the two clamping rods 4, which is used to drive the clamping rods 4 to press against the top surface of the building or the ground after being pulled. Specifically, when the cross bar 3 has a tendency to turn downward at the far end and upward at the near end, the follow-up traction mechanism located on the upper side drives the clamping rod 4 located on the upper side to press against the top surface of the building, and the follow-up traction mechanism located on the lower side drives the clamping rod 4 located on the lower side to press against the ground of the building; A distal wire rope 51, one end of which is connected to the distal end of the crossbar 3, and the other end of which is connected to the follow-up traction mechanism located above, and provides a pulling force for the corresponding follow-up traction mechanism; and The proximal steel wire rope 52 has one end connected to the proximal end of the cross bar 3 and the other end connected to the follow-up traction mechanism located below, and provides a pulling force for the corresponding follow-up traction mechanism.

[0021] Among them, the middle support mechanism 2 includes a telescopic joint 21 and an adjustment structure for adjusting and locking the total length of the telescopic joint 21. The two ends of the telescopic joint 21 are respectively connected to the two support frames 1, and the clamping rod 4 is arranged along the length direction of the telescopic joint 21 and is slidably arranged at one end of the telescopic joint 21; the adjustment structure can be an automatic lifting device such as a cylinder, a hydraulic cylinder, an electric push rod, a scissor lift, or a manual lifting device, as long as the structure or device can realize the adjustment and locking of the distance between the two support frames 1.

[0022] And, refer to Figure 2 and Figure 3 , the follow-up traction mechanism includes: A slider 61 is slidably disposed at one end of the telescopic joint 21; The hanging member 62 is fixedly connected to the slider 61 and is used for hanging the distal wire rope 51 or the proximal wire rope 52; The first rack 63 is fixed to the slider 61 and arranged along the length direction of the telescopic joint 21; The second rack 64 is fixed to the clamping rod 4 and arranged along the length direction of the clamping rod 4; The gear 65 is rotatably mounted on one end of the telescopic joint 21 and is located between the first rack 63 and the second rack 64 . The gear 65 is meshedly connected with the first rack 63 and the second rack 64 .

[0023] In this way, when using the mobile device of the present application, first move the mobile device of the present application to the construction work position, adjust the distance between the two support frames 1 through the middle support mechanism 2, so that the upper support mechanism 11 and the lower support mechanism 12 are respectively pressed against the top surface of the building and the ground, and then use the upper support mechanism 11 and the lower support mechanism 12 to lock to prevent the mobile device from moving during operation, and then the operator can hang the safety belt on the safety rope hanging point 31 at the far end of the cross bar 3 before operation.

[0024] When the operator falls unexpectedly, under the action of the operator's weight, the cross bar 3 has a tendency to flip downward at the far end and flip upward at the near end, so the far end wire rope 51 at the far end of the cross bar 3 pulls the slider 61 located above to move downward, and the slider 61 drives the corresponding gear 65 to rotate through the first rack 63 on it when it moves downward, and the gear 65 drives the second rack 64 meshed with it and the corresponding clamping rod 4 to move upward when it rotates, and the clamping rod 4 located above can be tightly pressed against the top surface of the building when it moves upward; similarly, the near end wire rope 52 at the near end of the cross bar 3 pulls the slider 61 located below to move upward, which can drive the clamping rod 4 located below to move downward and press against the ground of the building, thereby the mobile device of the present application can be more firmly locked between the top surface of the building and the ground, which can greatly improve the safety of the operator when working at a height. Moreover, the greater the impact force of the operator's fall, the greater the degree of pressing of the clamping rod 4 against the top surface of the building and the ground, providing a strong guarantee for the operator at a height. It also solves the problem of indoor personnel having no safety belt hanging points when working at height, thereby achieving the goal of protecting the safety of the workers and preventing the occurrence of safety accidents.

[0025] In addition, in order to further improve the security of the mobile device of the present application, refer to Figure 1 , the distance between the rotation point of the cross bar 3 on the middle support mechanism 2 and the far end of the cross bar 3 is greater than the distance from the near end of the cross bar 3, and a plurality of far end steel wires 51 connected to the follow-up traction mechanism located above are arranged at the far end of the cross bar 3; it should be noted that, considering that the sliding strokes of the slider 61 corresponding to the far end steel wires 51 and the near end steel wires 52 are inconsistent, the lengths of the two vertical rods are set to be inconsistent, for example, the length of the upper vertical rod extending above the support frame 1 is less than the length of the lower vertical rod extending below the support frame 1, so as to ensure that both vertical rods can simultaneously press against the top surface and the ground of the building when the cross bar 3 is turned over. In addition, a friction block 41 is fixedly connected to the end of the clamping rod 4 away from the cross bar 3, which can increase the contact area between the clamping rod 4 and the top surface and the ground of the building, and improve the locking effect.

[0026] At the same time, refer to Figure 1 and Figure 4 The upper supporting mechanism 11 and the lower supporting mechanism 12 mentioned above both include: A plurality of legs 71 are provided and hingedly mounted on the support frame 1. In this embodiment, four legs 71 are provided to improve the stability of the support frame 1; Universal wheels 72 are installed at one end of the leg 71 away from the support frame 1, and at least two universal wheels 72 have a self-locking function, and specifically, all four universal wheels 72 are self-locking universal wheels 72; The vibration reduction device 73 is connected between the support leg 71 and the support frame 1 and is used to provide a buffer for the turning of the support leg 71 on the support frame 1 . Specifically, the vibration reduction device 73 may be a hydraulic vibration reduction device 73 .

[0027] In this way, the arrangement of multiple legs 71 can ensure the stability of the support frame 1 while also being able to adaptively and autonomously adjust the angle between the legs 71 and the support frame 1 according to the actual contact surface of the universal wheel 72 when the ground or top surface is uneven or has a slope, so as to ensure the stable tightness and support effect of the support frame 1.

[0028] And, as a manual adjustment implementation method of the adjustment structure, refer to Figure 1 and Figure 5 The telescopic joint 21 includes a large vertical rod 211 and a small vertical rod 212 which are slidably sleeved. The adjustment structure includes a plurality of positioning holes 2111 spaced apart along the length direction of the large vertical rod 211 and a fixing hole 2121 provided on the small vertical rod 212. A latch 213 is provided in the fixing hole 2121 and one of the positioning holes 2111. The large vertical rod 211 and the small vertical rod 212 are bolted and fixed to the corresponding support frame 1, and the ends of the large vertical rod 211 and the small vertical rod 212 which are away from each other are provided with a hollow portion 214, and the clamping rod 4 is slidably provided in the hollow portion 214.

[0029] In this way, when adjusting the spacing between the two support frames 1, the latch 213 can be pulled out first, and then the small pole 212 can be moved in the large pole 211 to change the spacing between the two support frames 1, so that the universal wheels 72 on the upper and lower support frames 1 are respectively in contact with the top surface of the building and the ground, and then the latch 213 is inserted into the fixing hole 2121 and the appropriate positioning hole 2111 to achieve the locking of the overall length of the telescopic joint 21. Moreover, since the large pole 211 and the small pole 212 are bolted and fixed to the support frame 1, they can be flexibly disassembled after construction and then conveniently assembled when needed, which greatly improves the convenience of the mobile device of the present application when used. Therefore, compared with setting the adjustment structure as an automatic lifting device, in this embodiment, the adjustment structure is set to a manual adjustment method such as a latch 213, although it is not very convenient to adjust the spacing, it can improve the convenience of using the mobile device. In actual use, the adjustment structure can be flexibly adjusted automatically and manually according to actual engineering needs.

[0030] The implementation principle of a mobile device capable of fastening a safety belt for indoor high-altitude work in the embodiment of the present application is as follows: When using the mobile device of the present application, first move the mobile device of the present application to the construction work position, adjust the distance between the two support frames 1 through the middle support mechanism 2, so that the upper support mechanism 11 and the lower support mechanism 12 are respectively pressed against the top surface of the building and the ground, and then use the upper support mechanism 11 and the lower support mechanism 12 to lock to prevent the mobile device from moving during operation, and then the operator can hang the safety belt on the safety rope hanging point 31 at the far end of the cross bar 3 before operation.

[0031] When the operator falls unexpectedly, under the action of the operator's weight, the cross bar 3 has a tendency to flip downward at the far end and flip upward at the near end, so the far end wire rope 51 at the far end of the cross bar 3 pulls the slider 61 located above to move downward, and the slider 61 drives the corresponding gear 65 to rotate through the first rack 63 on it when it moves downward, and the gear 65 drives the second rack 64 meshed with it and the corresponding clamping rod 4 to move upward when it rotates, and the clamping rod 4 located above can be tightly pressed against the top surface of the building when it moves upward; similarly, the near end wire rope 52 at the near end of the cross bar 3 pulls the slider 61 located below to move upward, which can drive the clamping rod 4 located below to move downward and press against the ground of the building, thereby the mobile device of the present application can be more firmly locked between the top surface of the building and the ground, which can greatly improve the safety of the operator when working at a height. Moreover, the greater the impact force of the operator's fall, the greater the degree of pressing of the clamping rod 4 against the top surface of the building and the ground, providing a strong guarantee for the operator at a height. It also solves the problem of indoor personnel having no safety belt hanging points when working at height, thereby achieving the goal of protecting the safety of the workers and preventing the occurrence of safety accidents.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
