Description

Technical Field

[0001] The invention relates to a pole expansion installation structure, in particular to a pole anti-falling expansion device. Background Art

[0002] The current pole expansion structure is divided into a pole reserved expansion structure and a pole post-installation expansion structure. The pole post-installation expansion structure is generally fixed on the pole in the form of a clamp, which generally includes a clamp and an expansion bracket arranged on the clamp. Although the current pole post-installation expansion structure in the form of a clamp can be installed and expanded according to actual needs, its fixing reliability is poor and there is a risk of loosening and falling off, resulting in damage to the expansion equipment and the resulting safety hazards.

[0003] For example, the Chinese patent publication number CN214409092U, the invention is called a pole clamp for convenient installation of an electric meter box, comprising a first semicircular clamp and a second semicircular clamp, and a mounting plate is provided on the outer wall of the first semicircular clamp. The pole clamp for convenient installation of an electric meter box of this scheme is convenient for installing the electric meter box and convenient for adjusting the installation position of the clamp on the pole; however, it also has poor fixing reliability and the risk of loosening and falling off. Summary of the invention

[0004] The purpose of the present invention is to provide a pole-mounted anti-falling expansion device which can effectively solve the problem that the expansion device and the expansion equipment fall off due to the loosening of the pole clamp, causing equipment damage and posing a safety hazard.

[0005] The technical solution of the present invention is:

[0006] A pole-mounted anti-falling expansion device, comprising:

[0007] The main hoop comprises a plurality of main hoop plates, the main hoop plates of the main hoop are connected by bolts, the main hoop is fixed on the rod, and at least one of the main hoop plates is provided with an expansion bracket;

[0008] The blocking hoop and the blocking hoop plates are connected by bolts. The blocking hoop plates are fixed on the pole tightly. The blocking hoop is located below the main hoop, and the distance between the blocking hoop and the main hoop is the set value L. The expansion device is installed on the expansion bracket, and the weight of the expansion device is carried by the main hoop. The blocking hoop is located below the main hoop and is used to block the main hoop; if the main hoop becomes loose and falls off during use, the main hoop can be blocked by the blocking hoop to prevent the main hoop and the expansion device from falling off further. Therefore, it can effectively solve the problem that the expansion device and the expansion device fall off due to the loosening of the hoop on the pole, causing equipment damage and safety hazards.

[0009] Preferably, it further comprises an anti-leaking mechanism, wherein both ends of the main hoop plate are provided with ear plates, and the ear plates are provided with ear plate holes, and the anti-leaking mechanism comprises:

[0010] An upper fixing member, which is arranged on the outer wall of one of the main hoop plates and is provided with a blocking rod upper through hole;

[0011] A lower fixing member, which is arranged on the outer wall of one of the blocking hoop plates and is provided with a blocking rod lower through hole;

[0012] The ear plate hole blocking rod passes through the lower through hole of the blocking rod and the upper through hole of the blocking rod in sequence, and a limit block is provided on the ear plate hole blocking rod, and the limit block is located above the upper fixing member. The ear plate hole blocking rod is close to the ear plate hole of the main hoop plate, and is used to block the bolt from passing through the ear plate hole;

[0013] The locking mechanism is arranged on the lower fixing part, and the locking mechanism fixes the ear plate hole blocking rod in the lower through hole of the blocking rod; when the blocking clamp is tightly clamped and fixed on the rod, the locking mechanism releases the ear plate hole blocking rod in the lower through hole of the blocking rod, so that the ear plate hole blocking rod can be pulled out upwards.

[0014] Although a blocking hoop is installed under the main hoop, when the main hoop becomes loose and falls off, it can block the main hoop and prevent the main hoop and expansion equipment from falling; however, in actual construction, since the expansion equipment is only installed on the expansion bracket of the main hoop (the blocking hoop is not installed with the expansion equipment), it is often the case that operators do not install the blocking hoop as required and miss installing the blocking hoop. In order to solve this problem, this solution specially sets up an anti-missing installation mechanism, which requires operators to install the blocking hoop first before installing the main hoop. Specifically, the operator first installs the blocking clamp, and clamps and fixes the blocking clamp on the rod. At this time, the locking mechanism releases the ear plate hole blocking rod in the lower through hole of the blocking rod, so that the ear plate hole blocking rod can be pulled out upwards; then, the operator pulls the ear plate hole blocking rod out from the lower through hole of the blocking rod and the upper through hole of the blocking rod from bottom to top; then, the main clamp is installed within the set spacing above the blocking clamp, and the main clamp is clamped and fixed on the rod (the operator installs the blocking clamp first as required, and the installation of the main clamp will not be affected by the anti-missing installation mechanism). If the operator wants to directly install the main clamp, since the ear plate hole blocking rod is close to the ear plate hole of the main hoop plate, it is used to block the bolt from passing through the ear plate hole, which makes it impossible for the bolt to pass through the ear plate hole of the main hoop plate where the ear plate hole blocking rod is located, and thus the main clamp cannot be clamped and fixed on the rod, forcing the operator to install the blocking clamp first; thus, it can effectively solve the problem that the operator does not install the blocking clamp as required and misses to install the blocking clamp.

[0015] Preferably, the locking mechanism includes a locking hole provided on the outer side of the ear plate hole blocking rod, a locking pin inserted in the locking hole, a radial hole provided in the lower fixing member, a push rod embedded in the radial hole, and a connecting member connecting the push rod and the locking pin, wherein the push rod is parallel to the locking pin, the push rod is interference fit with the radial hole, and one end of the push rod extends into the inner side of the inner wall of the blocking hoop. In the process of the blocking hoop clamping the rod, the push rod will abut against the outer wall of the rod, and overcome the friction between the push rod and the radial hole, so that the push rod is pushed out of the blocking hoop, and the locking pin is driven to move out of the locking hole through the connecting member. When the blocking hoop is clamped and fixed on the rod, the push rod is flush with the inner wall of the blocking hoop, and at this time, the locking pin moves to the outside of the locking hole, so that the locking mechanism releases the ear plate hole blocking rod in the lower through hole of the blocking rod, and the operator can pull the ear plate hole blocking rod out of the lower through hole of the blocking rod and the upper through hole of the blocking rod from bottom to top.

[0016] Preferably, the radial hole extends along the radial direction of the blocking hoop plate. In this way, when the blocking hoop is clamped on the rod, it is helpful to push the ejector rod out of the blocking hoop.

[0017] Preferably, a receiving groove is provided on the outer side surface of the lower fixing member, and the connecting member is located in the receiving groove.

[0018] Preferably, the upper through hole of the blocking rod extends along the axial direction of the main hoop plate, and the lower through hole of the blocking rod extends along the axial direction of the blocking plate.

[0019] Preferably, reinforcing plates are provided between the ear plates at both ends of the main hoop plate and the outer wall of the main hoop plate, and one of the reinforcing plates constitutes the upper fixing member. In this way, on the one hand, the structure of the main hoop plate can be strengthened by the reinforcing plates, and on the other hand, by constituting the upper fixing member with one of the reinforcing plates, costs can be saved.

[0020] Preferably, the lower fixing member is fixed to the outer wall of the blocking hoop plate by bolts or welding.

[0021] As preferably, the blocking hoop plates are two. In this way, it is convenient for the operator to install the blocking hoop so that the blocking hoop is tightly fixed on the rod.

[0022] Preferably, the expansion bracket includes a radial expansion rod and a vertical expansion rod disposed at the end of the radial expansion rod, the radial expansion rod extends radially along the main hoop plate, the radial expansion rod is provided with a plurality of mounting holes, and the vertical expansion rod is also provided with a plurality of mounting holes.

[0023] The beneficial effect of the present invention is that it can effectively solve the problem that the expansion device and the expansion equipment fall off due to the loosening of the clamp on the pole, causing damage to the equipment and bringing potential safety hazards.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0033] Specific embodiment 1: Figure 1 , Figure 2 , Figure 3 As shown, a pole-mounted anti-falling expansion device includes a main hoop 1 and a blocking hoop 2. The main hoop includes a plurality of main hoop plates 1.1. In this embodiment, the blocking hoop has three blocking hoop plates. Of course, the main hoop plates of the main hoop can also be set to two or four as needed. The main hoop plates of the main hoop are connected by bolts. The main hoop is fixed on the pole. At least one of the main hoop plates is provided with an expansion bracket 1.2. In this embodiment, each main hoop plate is provided on the expansion bracket. The expansion bracket is used to install the expansion equipment. The expansion equipment is installed on the expansion bracket, and the weight of the expansion equipment is borne by the main hoop.

[0034] The blocking hoop 2 has several blocking hoop plates 2.1. In this embodiment, the blocking hoop has two blocking hoop plates. In this way, it is convenient for the operator to install the blocking hoop so that the blocking hoop is tightly fixed on the rod. Of course, the blocking hoop plates of the blocking hoop can also be three or four. The blocking hoop plates of the blocking hoop are connected by bolts. The blocking hoop is tightly fixed on the rod. The blocking hoop is located below the main hoop, and the distance between the blocking hoop and the main hoop is a set value L.

[0035] The expansion device is installed on the expansion bracket, and the weight of the expansion device is carried by the main clamp. The blocking clamp is located below the main clamp and is used to block the main clamp. Since the blocking clamp does not carry the expansion device, the blocking clamp fixed on the pole will not usually loosen. If the main clamp becomes loose and falls off during use, the blocking clamp can be used to block the main clamp to prevent the main clamp and the expansion device from falling off further. This can effectively solve the problem of the expansion device and the expansion device falling off due to the loose clamp on the pole, causing equipment damage and safety hazards. On the other hand, if the power inspection personnel find that the main clamp is against the blocking clamp during the inspection, it can be determined that the main clamp is loose and falling off, so as to facilitate maintenance.

[0036] In this embodiment, the set value L is 10-25 cm. If the distance between the blocking clamp and the main clamp is too large, when the main clamp becomes loose and falls off, it is not conducive for the blocking clamp to block the main clamp. If the distance between the blocking clamp and the main clamp is too small, it is not conducive for power inspection personnel to identify whether the main clamp is against the blocking clamp.

[0037] Further, such as Figure 1 , Figure 2 As shown, both ends of the main hoop plate 1.1 are provided with ear plates 1.3, and the ear plates are provided with ear plate holes. The bolts of the main hoop pass through the corresponding ear plate holes. The main hoop plate is an arc hoop plate. Reinforcement plates 1.4 are provided between the ear plates at both ends of the main hoop plate and the outer wall of the main hoop plate. The reinforcement plate is perpendicular to the axis of the main hoop plate.

[0038] The expansion bracket 1.2 includes a radial expansion rod 1.21 fixed on the outer wall of the main hoop plate and a vertical expansion rod 1.22 provided at the end of the radial expansion rod. The radial expansion rod extends radially along the main hoop plate. The radial expansion rod is provided with a plurality of mounting holes. The vertical expansion rod is also provided with a plurality of mounting holes. The vertical expansion rod extends axially along the main hoop plate.

[0039] Further, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a rod-mounted anti-fall-off expansion device also includes an anti-missing mechanism 3. The anti-missing mechanism includes an upper fixing member 3.1, a lower fixing member 3.4, an ear plate hole blocking rod 3.2 and a locking mechanism. The upper fixing member 3.1 is arranged on the outer wall of one of the main hoop plates, and the upper fixing member is provided with an upper through hole 3.3 of the blocking rod. In this embodiment, a reinforcing plate in the main hoop plate constitutes the upper fixing member. The lower fixing member 3.4 is arranged on the outer wall of one of the blocking hoop plates. The lower fixing member is provided with a lower through hole 3.5 of the blocking rod. The ear plate hole blocking rod passes through the lower through hole of the blocking rod and the upper through hole of the blocking rod in sequence. A limit block 3.12 is provided on the ear plate hole blocking rod, and the limit block is located above the upper fixing member. The ear plate hole blocking rod is close to the ear plate hole of the main hoop plate, and is used to block the bolt from passing through the ear plate hole. The locking mechanism is arranged on the lower fixing member. The locking mechanism fixes the ear plate hole blocking rod in the lower through hole of the blocking rod. When the blocking hoop is tightly fixed on the rod, the locking mechanism releases the ear plate hole blocking rod in the lower through hole of the blocking rod, so that the ear plate hole blocking rod can be pulled out upward. In this embodiment, the locking mechanism includes a locking hole 3.6 arranged on the outer side of the ear plate hole blocking rod, a locking pin 3.7 inserted in the locking hole, a radial hole 3.9 arranged in the lower fixing member, a push rod 3.10 embedded in the radial hole, and a connecting member 3.8 connecting the push rod and the locking pin. The push rod is parallel to the locking pin, and the push rod is interference fit with the radial hole. A push rod through hole 3.11 is provided on the blocking hoop plate where the lower fixing member is located. One end of the push rod extends into the inner side of the inner wall of the blocking hoop plate. Specifically, one end of the push rod passes through the push rod through hole and extends into the inner side of the inner wall of the blocking hoop plate, and the connecting member is connected to the other end of the push rod.

[0040] Although a blocking hoop is installed under the main hoop, when the main hoop becomes loose and falls off, it can block the main hoop and prevent the main hoop and the expansion equipment from falling; however, in actual construction, since the expansion equipment is only installed on the main hoop expansion bracket (the blocking hoop is not installed with the expansion equipment), it is often the case that operators fail to install the blocking hoop as required and miss to install the blocking hoop. In order to solve this problem, this embodiment specifically sets up an anti-missing installation mechanism, which requires the operator to install the blocking hoop first before installing the main hoop. Specifically,

[0041] The operator first installs the blocking clamp and clamps the blocking clamp tightly on the rod. At this time, the locking mechanism releases the ear plate hole blocking rod in the lower through hole of the blocking rod, so that the ear plate hole blocking rod can be pulled out. Specifically, in the process of the blocking clamp clamping on the rod, the push rod will be against the outer wall of the rod, and overcome the friction between the push rod and the radial hole, so that the push rod is pushed out of the blocking clamp, and the locking pin is driven to move out of the locking hole through the connecting piece. When the blocking clamp is clamped and fixed on the rod, the push rod is flush with the inner wall of the blocking hoop plate. At this time, the locking pin moves to the outside of the locking hole, so that the locking mechanism releases the ear plate hole blocking rod in the lower through hole of the blocking rod, and the operator can pull the ear plate hole blocking rod out of the lower through hole of the blocking rod and the upper through hole of the blocking rod from bottom to top. Then, the operator pulls the ear plate hole blocking rod out of the lower through hole of the blocking rod and the upper through hole of the blocking rod from bottom to top. Then, install the main hoop within the set spacing above the blocking hoop, and clamp and fix the main hoop on the rod (the operator installs the blocking hoop first as required, and the main hoop will not be affected by the anti-missing installation mechanism). If the operator wants to install the main hoop directly, since the ear plate hole blocking rod is close to the ear plate hole of the main hoop plate, it is used to block the bolt from passing through the ear plate hole, which makes it impossible for the bolt to pass through the ear plate hole of the main hoop plate where the ear plate hole blocking rod is located, and thus the main hoop cannot be clamped and fixed on the rod, forcing the operator to install the blocking hoop first; thus, it can effectively solve the problem of operators not installing the blocking hoop as required and missing the blocking hoop.

[0042] The radial hole extends along the radial direction of the blocking hoop plate. In this way, when the blocking hoop is clamped on the rod, it is helpful to push the push rod out of the blocking hoop. A receiving groove is provided on the outer surface of the lower fixing member, and the connecting member is located in the receiving groove. The upper through hole of the blocking rod extends along the axial direction of the main hoop plate, and the lower through hole of the blocking rod extends along the axial direction of the blocking plate. The lower fixing member is fixed to the outer wall of the blocking hoop plate by bolts or welding.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
