Description

Technical Field

[0001] This invention relates to a pole-mounted anti-fall device, specifically a double-safety pole-mounted anti-fall device. Background Technology

[0002] Preventing falls from heights is a perpetual safety concern in power engineering construction. Falls from heights can be categorized into falls on personnel and falls on objects. In the latter case, tools left floating in mid-air (i.e., workers placing tools on the crossarms of utility poles or other supports during construction) are highly susceptible to falling objects, creating safety hazards. To address this issue, the common method is to hang tools in tool bags, which are then hooked onto the crossarms of utility poles or other supports. While this method can mitigate the risk of tools floating in mid-air to some extent, it often results in workers leaving tools unattended due to the difficulty of finding suitable locations to hang the tool bags, creating further safety risks. Summary of the Invention

[0003] The purpose of this invention is to overcome the safety hazard caused by tools floating in the air by providing a double-safety pole-mounted anti-fall device that allows workers to easily fix tool bags to utility poles as needed.

[0004] The technical solution of this invention is: A double-safety pole-mounted anti-fall device includes: Ratchet tightening belt; The hanging device includes a vertically upward side plate, a horizontal hanging plate disposed below the vertically upward side plate, hanging holes disposed on the horizontal hanging plate, and a vertically downward side plate disposed below the horizontal hanging plate. The vertically upward side plate has a tightening upper strap passage, the upper part of the vertically downward side plate is connected to the horizontal hanging plate, and the vertically downward side plate has a tightening lower strap passage. The ratchet tightening belt consists of two sections. One section passes through the tightening upper belt opening of the vertically upward side plate, and the vertically upward side plate is held and fixed to the pole by the ratchet tightening belt. The other section passes through the tightening lower belt opening of the vertically downward side plate, and the vertically downward side plate is held and fixed to the pole by the ratchet tightening belt.

[0005] The specific usage of the double-safety pole-mounted anti-fall device in this solution is as follows: The vertical upper side plate is secured to a specific position on the pole using ratchet tightening straps; similarly, the vertical lower side plate is secured to a specific position on the pole using ratchet tightening straps. These two ratchet tightening straps then secure the hanging device to a specific position on the pole. Workers can then hang the tool bag on the hooks in the hanging holes of the horizontal hanging plate. This allows workers to easily secure the tool bag to the pole as needed, effectively solving the safety hazard caused by tools floating in mid-air. Furthermore, using two ratchet tightening straps to secure the hanging device to the pole prevents the tool bag from slipping off due to one ratchet tightening strap being loose or coming undone during use, effectively improving safety and reliability.

[0006] Preferably, the mounting device further includes a compression spring, a mounting hole baffle rotatably mounted on the lower surface of the horizontal mounting plate via a hinge shaft, a horizontal guide rod mounted on the horizontal mounting plate, a guide hole mounted on the upper part of the vertical downward side plate, and a baffle push rod mounted on the upper part of the vertical downward side plate. The horizontal guide rod is inserted into the guide hole, and the vertical downward side plate can slide along the horizontal guide rod. The mounting hole baffle and the baffle push rod are located on the same side of the vertical downward side plate, and the baffle push rod and the electric pole are located on opposite sides of the vertical downward side plate. The compression spring is used to provide elastic force to move the vertical downward side plate away from the electric pole along the horizontal guide rod.

[0007] When the ratchet tightening strap on the vertical lower side plate is tightly secured to the pole and the vertical lower side plate is pressed against the outer surface of the pole, the hanging hole baffle is suspended below the horizontal hanging plate by its own weight through the hinge shaft. At this time, the hanging hole baffle is located on one side of the hanging hole. When the ratchet tightening strap on the vertical upper side plate is tightly secured to the pole, as the vertical lower side plate moves away from the pole along the horizontal guide rod, the baffle push rod will push the hanging hole baffle to rotate upward around the hinge shaft and cause the hanging hole baffle to seal the lower end of the hanging hole.

[0008] In the actual use of double-safety pole-mounted anti-fall devices, the following problem often occurs: After tightening the ratchet tightening strap on the vertical upward side plate and securing it to the pole, workers often neglect to tighten the ratchet tightening strap on the vertical downward side plate due to laziness. While this still secures the device to the pole for hanging tool bags, its safety and reliability are poor. To solve this problem, this solution improves the hanging device. Specifically, after tightening the ratchet tightening strap on the vertical upward side plate and securing it to the pole, if the ratchet tightening strap on the vertical downward side plate is not tightened, the vertical downward side plate... Under the action of the compression spring, the tool bag will move away from the pole along the horizontal guide rod. During this process, the baffle push rod will push the hanging hole baffle to rotate upward around the hinge axis, and block the lower end of the hanging hole through the hanging hole baffle. At this time, because the lower end of the hanging hole is blocked by the hanging hole baffle, the hook on the tool bag cannot be hung on the hanging hole, thus forcing the operator to tighten the ratchet tightening belt on the vertical lower side plate, so that the vertical lower side plate is close to the outer side of the pole. At this time, the hanging hole baffle is suspended below the horizontal hanging plate by its own weight through the hinge axis, so that the hanging hole baffle is located on one side of the hanging hole, so that the operator can hang the tool bag on the hanging hole of the horizontal hanging plate through the hook. Therefore, the hanging device of this solution can effectively solve the problem of the operator's laziness in not tightening the ratchet tightening belt on the vertical lower side plate, thus affecting the safety and reliability of use, without affecting its normal use (i.e., the operator tightens the ratchet tightening belt on the vertical upper side plate and the vertical lower side plate according to the specifications).

[0009] Preferably, the lower surface of the horizontal mounting plate is provided with a receiving groove. One end of the receiving groove is connected to the side of the horizontal mounting plate facing the pole, and the other end of the receiving groove is closed. The horizontal guide rod is disposed in the receiving groove, and the upper end of the vertical lower side plate is located in the receiving groove. When the vertical lower side plate abuts against the other end of the receiving groove, the baffle push rod abuts against the hanging hole baffle, the hanging hole baffle seals the lower port of the hanging hole, and the baffle push rod is located below the hanging hole baffle. In this way, the compactness of the mounting device mechanism can be improved.

[0010] Preferably, the other end face of the receiving groove is provided with a threaded hole, the transverse guide rod is made of bolts, the bolts are connected to the threaded hole, and a head receiving hole is provided on the side face of the vertical lower side plate facing the head of the bolt. This facilitates the installation and manufacturing of the transverse guide rod.

[0011] Preferably, the mounting device also includes a guide hole provided on the vertically downward side plate and a sliding push rod that slides along the guide hole. Both ends of the sliding push rod are provided with limit baffles. A compression spring is sleeved on the sliding push rod. One end of the compression spring abuts against the limit baffle facing the pole, and the other end of the compression spring abuts against the vertically downward side plate. One end of the sliding push rod abuts against the outer surface of the pole.

[0012] Preferably, a limiting baffle receiving hole is provided on the side of the vertically downward side plate facing the pole, and the other end of the compression spring abuts against the end face of the limiting baffle receiving hole on the vertically downward side plate.

[0013] Preferably, the vertical upper side panel is perpendicular to the horizontal hanging panel.

[0014] Preferably, the vertical lower side panel is perpendicular to the horizontal hanging panel.

[0015] Preferably, the vertical side panel and the horizontal hanging panel are integrally formed.

[0016] The beneficial effects of this invention are that workers can conveniently fix tool bags to utility poles as needed, effectively solving the safety hazards caused by tools floating in the air. Attached Figure Description

Detailed Implementation

[0020] Specific Implementation Example 1: As shown in the example Figure 1 , Figure 2As shown, a double-safety pole-mounted anti-fall device includes a ratchet tightening strap 1 and a hanging device. The ratchet tightening strap is existing technology. The hanging device includes a vertically upward side plate 2, a horizontal hanging plate 3 located at the lower part of the vertically upward side plate, a hanging hole 3.1 located on the horizontal hanging plate, and a vertically downward side plate 4 located below the horizontal hanging plate. The hanging hole penetrates the upper and lower surfaces of the horizontal hanging plate. The vertically upward side plate has a tightening upper strap passage 2.1. The upper part of the vertically downward side plate is connected to the horizontal hanging plate, and the vertically downward side plate has a tightening lower strap passage 4.1. There are two ratchet tightening straps 1. One ratchet tightening strap passes through the tightening upper strap passage of the vertically upward side plate, and the vertically upward side plate is tightly fixed to the pole 5 by the ratchet tightening strap; the other ratchet tightening strap passes through the tightening lower strap passage of the vertically downward side plate, and the vertically downward side plate is tightly fixed to the pole 5 by the ratchet tightening strap.

[0021] The specific use of the double-safety pole-mounted anti-fall device in this embodiment is as follows. The vertical upper side plate is secured to a specific position on the pole using ratchet tightening straps; similarly, the vertical lower side plate is secured to a specific position on the pole using ratchet tightening straps. These two ratchet tightening straps then secure the hanging device to a specific position on the pole. Workers can then hang the tool bag on the hooks in the hanging holes of the horizontal hanging plate. This allows workers to easily secure the tool bag to the pole as needed, effectively solving the safety hazard caused by tools floating in mid-air. Furthermore, using two ratchet tightening straps to secure the hanging device to the pole prevents the tool bag from slipping off due to one ratchet tightening strap being loose or coming undone during use, effectively improving safety and reliability.

[0022] In this embodiment, the vertically upward side plate is perpendicular to the horizontal hanging plate. The vertically downward side plate is perpendicular to the horizontal hanging plate. The vertically upward side plate and the horizontal hanging plate are integrally formed. When the ratchet tightening strap on the vertically upward side plate holds and fixes the vertically upward side plate to the pole, the horizontal hanging plate is horizontally distributed.

[0023] Furthermore, such as Figure 1 , Figure 2As shown, the mounting device also includes a compression spring 6, a mounting hole baffle 14 rotatably mounted on the lower surface of the horizontal mounting plate via a hinge shaft 13, a horizontal guide rod 11 mounted on the horizontal mounting plate, a guide hole 12 mounted on the upper part of the vertical lower side plate, and a baffle push rod 9 mounted on the upper part of the vertical lower side plate. The horizontal guide rod is inserted into the guide hole to connect the upper part of the vertical lower side plate to the horizontal mounting plate. The vertical lower side plate can slide along the horizontal guide rod. The hinge shaft is perpendicular to the horizontal guide rod. The mounting hole baffle and the baffle push rod are located on the same side of the vertical lower side plate. Specifically, the lower surface of the horizontal mounting plate is provided with a receiving groove 10. One end of the receiving groove is connected to the side of the horizontal mounting plate facing the pole, and the other end of the receiving groove is closed. The horizontal guide rod is disposed in the receiving groove. The upper end of the vertical lower side plate is located in the receiving groove.

[0024] When the ratchet tightening band on the vertical upper side plate grips and secures the vertical upper side plate to the pole, the baffle push rod and the pole are located on opposite sides of the vertical lower side plate, and the transverse guide rod extends radially along the pole. A compression spring provides elastic force to move the vertical lower side plate away from the pole along the transverse guide rod.

[0025] When the ratchet tightening strap on the vertical lower side plate is tightly fixed to the pole and the vertical lower side plate is close to the outer surface of the pole, the hanging hole baffle is suspended below the horizontal hanging plate through the hinge shaft under its own weight. At this time, the hanging hole baffle is located on one side of the hanging hole.

[0026] like Figure 2 As shown, when the ratchet tightening belt on the vertical upper side plate is tightly fixed to the pole, as the vertical lower side plate moves away from the pole along the horizontal guide rod, the baffle push rod will push the hanging hole baffle to rotate upward around the hinge axis, and cause the hanging hole baffle to seal the lower end of the hanging hole.

[0027] like Figure 2 As shown, when the vertically downward side plate abuts against the other end of the receiving groove, the baffle push rod abuts against the hanging hole baffle, the hanging hole baffle seals the lower port of the hanging hole, and the baffle push rod is located below the hanging hole baffle.

[0028] In the actual use of double-safety pole-mounted anti-fall devices, the following problem often occurs: After tightening the ratchet tightening strap on the vertical upward side plate and securing it to the pole, operators often neglect to tighten the ratchet tightening strap on the vertical downward side plate due to laziness. While this still secures the device to the pole for hanging tool bags, its safety and reliability are poor. To solve this problem, this solution improves the hanging device. Specifically, after tightening the ratchet tightening strap on the vertical upward side plate and securing it to the pole, if the ratchet tightening strap on the vertical downward side plate is not tightened, the vertical downward side plate will be subjected to the action of the compression spring. Moving the tool bag along the horizontal guide rod away from the pole until the lower vertical side plate abuts against the other end of the receiving groove, the baffle push rod pushes the hanging hole baffle to rotate upward around the hinge axis, sealing the lower end of the hanging hole. Because the hanging hole baffle seals the lower end of the hanging hole, the hook on the tool bag cannot be hung on the hanging hole, forcing the operator to tighten the ratchet tightening strap on the lower vertical side plate, making the lower vertical side plate close to the outer surface of the pole. At this point, the hanging hole baffle, under its own weight, is suspended below the horizontal hanging plate through the hinge axis, positioning the hanging hole baffle on one side of the hanging hole, allowing the operator to hang the tool bag on the hanging hole of the horizontal hanging plate using the hook. Therefore, this hanging device effectively solves the problem of operators neglecting to tighten the ratchet tightening strap on the lower vertical side plate, thus affecting the safety and reliability of the tool bag, without affecting its normal use (i.e., provided the operator tightens the ratchet tightening strap on both the upper and lower vertical side plates according to specifications).

[0029] Specifically, such as Figure 2 As shown, the mounting device also includes a guide hole 8 on the vertically downward side plate and a sliding push rod 7 that slides along the guide hole. The sliding push rod is parallel to the transverse guide rod. Limiting baffles 7.1 are provided at both ends of the sliding push rod. A compression spring 6 is sleeved on the sliding push rod, with one end of the compression spring abutting against the limiting baffle facing the pole and the other end abutting against the vertically downward side plate. In this embodiment, a limiting baffle receiving hole is provided on the side of the vertically downward side plate facing the pole, and the other end of the compression spring abuts against the end face of the limiting baffle receiving hole on the vertically downward side plate. When the ratchet tightening strap on the vertically upward side plate is tightly fixed to the pole, one end of the sliding push rod abuts against the outer surface of the pole.

[0030] Furthermore, such as Figure 2 As shown, the end of the baffle push rod 9 is also provided with an end ball 9.1, the outer diameter of which is larger than the outer diameter of the baffle push rod. When the vertically downward side plate abuts against the other end of the receiving groove, the end ball of the baffle push rod abuts against the hanging hole baffle, the hanging hole baffle seals the lower port of the hanging hole, and the baffle push rod is located below the hanging hole baffle.

[0031] Furthermore, a threaded hole is provided on the end face of the other end of the receiving groove, and the transverse guide rod is made of bolts, which are connected to the threaded hole. A head receiving hole is provided on the side face of the vertical lower side plate facing the head of the bolt. This facilitates the installation and fabrication of the transverse guide rod.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
