Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety protection technology, and in particular to a safety mounting system for the rails of a bridge crane in a brewing workshop. Background Technology
[0002] Traditional high-altitude safety protection technologies have systemic defects in bridge crane track maintenance operations. Existing technologies generally employ static protection schemes combining fixed support rods and safety ropes. Examples include installing transverse support rods on steel columns above the track beam and connecting them to safety ropes, or installing a pulley system with spring drums and wire ropes between the trolley and the bridge frame. While these schemes provide basic anchor points, they suffer from three main problems:
[0003] Firstly, the spacing between the fixed support poles is too large and the position of the safety rope attachment point cannot be dynamically adjusted as the workers move, which means that the safety belt needs to be frequently unhooked when crossing the gaps between the steel columns, creating a protective vacuum period.
[0004] Secondly, the temporary steel pipe anchor points or the double dead knot winding method lack stability and are prone to rope slippage due to vibration. In addition, no buffer device is configured, and the impact force of falling is directly transmitted to the human body.
[0005] Third, there is a risk of interference between the existing protection system and the moving parts of the crane. For example, when the safety rope crosses the maintenance door, a complex pulley frame needs to be installed. The synchronous adjustment technology of the protective rope and the trolley movement in the operation of the gantry crane is not yet mature, which increases the complexity of the equipment and reduces the efficiency of operation.
[0006] The aforementioned defects make it difficult for existing technology to meet the dynamic maintenance requirements of bridge crane tracks in a brewing workshop at a height of 6.5 meters. As a result, workers are forced to carry out track maintenance without continuous protection, creating a major safety hazard. Utility Model Content
[0007] The purpose of this utility model is to provide a safety connection system for the bridge crane track in a brewing workshop, which addresses the above-mentioned shortcomings and solves the problem that continuous protection cannot be provided when workers are inspecting the bridge crane track at a height of 6.5 meters in a brewing workshop.
[0008] This utility model is achieved through the following solution:
[0009] A safety mounting system for a bridge crane track in a brewing workshop includes a support mounting component, a connecting steel rope, and a support base. The support base is connected to a wall via a connector, and a support platform is provided on the support base to fix the connecting steel rope. Multiple support bases are arranged along the length of the track to be inspected, and the connecting steel rope is arranged across all support bases. The support mounting component is provided with a movable opening. The support mounting component can pass through the support platform via the movable opening.
[0010] Based on the structure of the above-mentioned bridge crane rail safety attachment system in a brewing workshop, the supporting attachment includes a safety rope, a limiting rod, a hook body, and a stop seat. The limiting rod is positioned across the bottom of the hook body, dividing the hook into upper and lower ring structures. The upper ring structure is used to contact the supporting steel rope, and the lower ring structure is used to cooperate with the safety rope. An opening slot is provided on the upper ring structure. The opening slot includes a first end and a second end. The stop seat is movably mounted on the first end of the opening through an elastic element. When the stop seat is in the upper limit position, the end face of the stop seat is set at a predetermined distance from the second end.
[0011] Based on the structure of the above-mentioned bridge crane rail safety coupling system in a brewing workshop, the size of the connecting steel rope is not less than the distance between the end face of the stop seat and the first end when the stop seat is in the upper limit position; and the size of the connecting steel rope is not greater than the distance between the end face of the stop seat and the first end when the stop seat is in the lower limit position.
[0012] Based on the structure of the above-mentioned bridge crane rail safety connection system in a brewing workshop, the thickness of the support platform is not greater than the distance between the end face of the stop seat and the first end when the stop seat is in the upper limit position.
[0013] Based on the structure of the above-mentioned bridge crane rail safety attachment system in a brewing workshop, the stop seat includes a support cylinder, a guide cylinder, a top cover, and a support spring; the guide cylinder is disposed on the support cylinder, and the top cover is disposed on the end of the guide cylinder away from the support cylinder; the guide cylinder and the support cylinder have a smooth transition; the support spring is disposed between the first end and the top cover.
[0014] Based on the structure of the above-mentioned bridge crane track safety attachment system in a brewing workshop, a first limiting ring is also provided on the side wall of the first end, and a second limiting ring is provided at the end of the support cylinder. The first limiting ring and the second limiting ring cooperate to limit the upper limit position of the stop seat.
[0015] Based on the structure of the above-mentioned bridge crane track safety attachment system in a brewing workshop, the ring surface size of the first limiting ring is not less than the end face distance of the second limiting ring from the first end.
[0016] Based on the structure of the above-mentioned bridge crane track safety attachment system in a brewing workshop, the guide cylinder has an overall conical structure, and the support cylinder has an overall cylindrical structure.
[0017] Based on the structure of the above-mentioned bridge crane rail safety attachment system in a brewing workshop, the support base includes a support platform and a connecting plate; the connecting plate is provided with a connecting hole, and the connecting plate is connected to the wall by expansion bolts; the support platform is set perpendicular to the connecting plate, and the support platform is provided with a steel rope clamping seat and a clamping lock hole; the bottom bolt of the steel rope clamping seat passes through the clamping lock hole and is locked by at least two bolts.

[0034] Example 1
[0035] like Figures 1-5 As shown, this utility model provides a technical solution:
[0036] A safety attachment system for a bridge crane track 4 in a brewing workshop includes, but is not limited to, a support attachment 1, a connecting steel rope 2, and a support base 3. The support base 3 is connected to the wall via a connector, and a support platform 31 for fixing the connecting steel rope 2 is provided on the support base 3. Multiple support bases 3 are provided along the length of the track 4 to be tested, and the connecting steel rope 2 is arranged across all support bases 3. The support attachment 1 is provided with a movable opening. The support attachment 1 can pass through the support platform 31 through the movable opening.
[0037] Based on the above structure, this solution specially sets the dimensions of the hook, support platform 31, and connecting steel rope 2 so that the opening of the support hook 1 can just pass through the support platform 31, but cannot pass through the connecting steel rope 2. This way, the support hook 1 does not need to be removed when passing through the support platform 31. It can simply pass through the movable opening of the support hook 1 through the support platform 31 to achieve continuous support, ensuring the safety of maintenance personnel during subsequent maintenance operations.
[0038] As an example, the support hook 1 may include a safety rope 11, a limiting rod 12, a hook body 13, and a stop seat 14; the limiting rod 12 is positioned across the bottom of the hook body 13, dividing the hook into upper and lower ring structures, the upper ring structure being used to contact the support steel rope, and the lower ring structure being used to cooperate with the safety rope 11; an opening groove is provided on the upper ring structure; the opening groove may include a first end 15 and a second end 16, and the stop seat 14 is movably mounted on the first end 15 of the opening by an elastic element, and when the stop seat 14 is in the upper limit position, the end face of the stop seat 14 is set at a predetermined distance from the second end 16.
[0039] Based on the above structure, the safety rope 11 and the support steel rope can be separated by setting the limiting rod 12 to avoid interference between the safety rope 11 and the support steel rope, thus ensuring the safety of the safety rope 11. At the same time, a movable fixed stop seat 14 is set. The movable stop seat is positioned at a predetermined distance from the second end 16 in the normal state. In this way, the entire support hanger 1 can pass through the support platform 31 at a predetermined interval without operating the stop seat 14, thus achieving continuous support.
[0040] As an example, the size of the connecting steel rope 2 is not less than the distance between the end face of the stop seat 14 and the first end 15 when the stop seat 14 is in the upper limit position; and the size of the connecting steel rope 2 is not greater than the distance between the end face of the stop seat 14 and the first end 15 when the stop seat 14 is in the lower limit position.
[0041] The thickness of the support platform 31 is not greater than the distance between the end face of the stop seat 14 and the first end 15 when the stop seat 14 is in the upper limit position.
[0042] Based on the above structure, by specially setting the size of the connecting steel rope 2 and the position of the stop seat 14 on the first end 15, the stop seat 14 can always limit the connecting steel rope 2, so that the connecting steel rope 2 is always restricted in the upper ring structure, while the reserved opening can pass through the support platform 31 to realize continuous support operation.
[0043] As an example, the stop seat 14 may include a support cylinder 141, a guide cylinder 142, a top cover 143, and a support spring 144; the guide cylinder 142 is disposed on the support cylinder 141, and the top cover 143 is disposed on the end of the guide cylinder 142 away from the support cylinder 141; the guide cylinder 142 and the support cylinder 141 are smoothly connected; the support spring 144 is disposed between the first end 15 and the top cover 143.
[0044] A first limiting ring 145 is provided on the side wall of the first end 15, and a second limiting ring 146 is provided at the end of the support cylinder 141. The first limiting ring 145 and the second limiting ring 146 cooperate to limit the upper limit position of the stop seat 14.
[0045] The annular surface dimension of the first limiting ring 145 is not less than the distance between the end face of the second limiting ring 146 and the first end 15. This prevents the first limiting ring 145 from disengaging from the second limiting ring 146, thus achieving a stable limiting operation.
[0046] As an example, the guide cylinder 142 has an overall conical structure, while the support cylinder 141 has an overall cylindrical structure.
[0047] Based on the above structure, the guide cylinder 142 is set as a conical structure. On the one hand, it can prevent slippage when the cover is extended or retracted, so that the construction personnel can release the support steel rope more efficiently. On the other hand, it can guide the support steel rope after the operation is completed, so that the support steel rope can slide out of the support connector 1 more quickly.
[0048] As an example, the support base 3 may include a support platform 31 and a connecting plate 32; the connecting plate 32 is provided with a connecting hole, and the connecting plate 32 is connected to the wall by an expansion bolt 33; the support platform 31 is set perpendicular to the connecting plate 32, and the support platform 31 is provided with a steel rope clamping seat 34 and a clamping locking hole 35; the bottom bolt of the steel rope clamping seat 34 passes through the clamping locking hole 35 and is locked by at least two bolts.
[0049] Based on the above structure, the steel rope clamp 34 can stably limit the position of the supporting steel rope and prevent the steel rope from falling off the support platform 31. The connecting plate 32 is fixed to the wall by the expansion bolt 33 to ensure the overall connection strength.
[0050] As an example, all the support seats 3 are at the same horizontal level. This ensures that the support steel cable remains straight throughout the track 4, preventing the cable from bending.
[0051] The supporting steel rope uses φ8mm stainless steel wire rope as the main material, with a tensile strength ≥1570MPa and excellent corrosion resistance.
[0052] At a height of 4.1.4 meters from the track, expansion bolts 33 are used to install support base 3. The support is made of 70mm*140mm*6mm steel plate, which is bent and punched. The steel wire rope is fixed to the fixed support by steel wire rope clips, and the spacing between the steel wire rope fixed supports is 6 meters.
[0053] The connecting bracket is equipped with an open-type high-strength hook (material 40Cr, yield strength ≥785MPa). The hook opening is equipped with a spring locking structure to ensure a stable connection and one-handed operation.
[0054] Open the hook opening spring lock pin, and the hook and wire rope can slide freely along the wire rope.
[0055] The operation process of this solution is optimized. When maintenance personnel move along track 4, they do not need to remove the hook. Continuous protection is achieved by sliding the hook, reducing the frequency of hook removal and removal by more than 90%.
[0056] Installation steps:
[0057] (1) Mark the installation position of the fixed bracket for measuring rail.
[0058] (2) Use M12 expansion bolts 33 to fix the bracket to the concrete column, with a horizontal error of ≤2mm.
[0059] (3) The wire rope is tightened at both ends by tensioners, with the pre-tension force controlled at 8-10kN and the sag ≤50mm.
[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
