Description

Technical Field

[0001] This utility model relates to the field of annular choke particle delivery, specifically a portable ladder device for annular choke particle delivery. Background Technology

[0002] In the delivery of circumferential choke particles, ladders are often required at the delivery point to meet the needs of personnel operating from height.

[0003] However, most existing ladders have fixed structures and cannot be flexibly adjusted in terms of opening angle. When used on soft or uneven ground, the small support surface results in poor stability and a risk of tilting or even falling over, which seriously affects work safety. Secondly, although some foldable ladders have a certain degree of portability, they are not securely fixed after folding and lack auxiliary support structures. When subjected to large loads, their overall strength is insufficient and they are difficult to adapt to high-intensity work scenarios such as frequent climbing and tool handling during the delivery of annular choke particles.

[0004] Therefore, in response to the specific needs of annular choke particle delivery operations, the development of a portable and highly stable ladder device is crucial for improving operational efficiency and ensuring operational safety. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable ladder device for dispensing annular flow obstruction particles, comprising a main ladder and an auxiliary ladder arranged in a V-shape, wherein the tops of the main ladder and the auxiliary ladder are hinged together, and multiple auxiliary ladders of different lengths are provided between the main ladder and the auxiliary ladder. When the auxiliary ladder is connected between the main ladder and the auxiliary ladder, the auxiliary ladder is used to fix the opening angle between the main ladder and the auxiliary ladder. When one end of the auxiliary ladder is connected to the lower part of the main ladder or the auxiliary ladder, the auxiliary ladder can be used to increase the support surface of the main ladder and the auxiliary ladder.

[0007] Preferably, the main ladder, the secondary ladder, and the auxiliary ladder each include two longitudinal beams and multiple transverse beams.

[0008] Preferably, the auxiliary ladder includes a ladder body, with a retaining sleeve on each of the two sides of the ladder body at opposite ends, and a rubber support foot on one end of the auxiliary ladder.

[0009] Preferably, the sleeve includes an arc-shaped plate fixed on the auxiliary ladder, the end of the arc-shaped plate is provided with a positioning hole, and the auxiliary ladder is provided with a screw and a nut that cooperate with the positioning hole.

[0010] Preferably, the bottommost crossbeam is provided with a second retainer.

[0011] Preferably, the main ladder has a handle in the middle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the combination of a herringbone hinge structure and auxiliary ladders of various specifications improves the structural stability. The main ladder and the auxiliary ladder can be fixed at the opening angle with the help of the auxiliary ladder to form a stable "A"-shaped frame. The auxiliary ladder connected in the middle and lower part can expand the support surface and maintain reliable support even on soft ground. The longitudinal and transverse beams made of high-strength aluminum alloy ensure the overall load-bearing capacity and meet the work load requirements.

[0014] 2. In this utility model, by setting up quick-detachable sleeve 1 and sleeve 2, the handling and storage are more convenient; the rubber support feet of the auxiliary ladder and the firm connection design of the sleeve reduce the climbing risk, and the auxiliary ladder can be adjusted to adapt to different working scenarios, thereby improving the efficiency and safety of the annular choke particle delivery operation.

[0023] Example 1

[0024] Please refer to Figure 1-5 As shown, this utility model provides a portable ladder device for dispensing annular flow obstruction particles, including a main ladder 1 and an auxiliary ladder 2 arranged in a V-shape. The tops of the main ladder 1 and the auxiliary ladder 2 are hinged. Multiple auxiliary ladders 3 of different lengths are provided between the main ladder 1 and the auxiliary ladder 2. When the auxiliary ladder 3 is connected between the main ladder 1 and the auxiliary ladder 2, the auxiliary ladder 3 is used to fix the opening angle between the main ladder 1 and the auxiliary ladder 2. When one end of the auxiliary ladder 3 is connected to the lower part of the main ladder 1 or the auxiliary ladder 2, the auxiliary ladder 3 can be used to increase the support surface of the main ladder 1 and the auxiliary ladder 2. The main ladder 1, the auxiliary ladder 2 and the auxiliary ladder 3 each include two longitudinal beams 4 and multiple transverse beams 5.

[0025] The main ladder 1 and the auxiliary ladder 2 are symmetrically arranged, and their tops are hinged together. There are multiple auxiliary ladders 3, preferably two. Both the main ladder 1 and the auxiliary ladder 2 are composed of two longitudinal beams 4 and multiple transverse beams 5. The longitudinal beams 4 are made of high-strength aluminum alloy square tubes. The two ends of the transverse beams 5 are fixed to the longitudinal beams 4 by high-strength aluminum alloy round tubes. The multiple transverse beams 5 are arranged at equal intervals. The two ends of the auxiliary ladders 3 can be fixed to the transverse beams 5 at the ends of the main ladder 1 and the auxiliary ladder 2, respectively, to facilitate the reinforcement of the opened main ladder 1 and the auxiliary ladder 2. One end of one of the auxiliary ladders 3 can be fixed to the transverse beam 5 in the lower part of the main ladder 1 or the auxiliary ladder 2 to reinforce the main ladder 1 or the auxiliary ladder 2.

[0026] Specifically, the auxiliary ladder 3 includes a ladder body 6, with a retaining sleeve on each of the two sides of the ladder body 6 at opposite ends, and a rubber support foot 7 at one end of the auxiliary ladder 3. The retaining sleeve includes an arc-shaped plate 8 fixed to the auxiliary ladder 3, with a positioning hole 9 at the end of the arc-shaped plate 8. The auxiliary ladder 3 is provided with a screw 10 and a nut 11 that cooperate with the positioning hole 9. The ladder body 6 is rectangular, and the retaining sleeve is fixed at both ends of the ladder body 6. The retaining sleeve is located on the top and bottom surfaces of the ladder body 6, respectively. The arc-shaped plate 8 on the retaining sleeve is made of a plastic plate with a certain degree of elasticity. One end of the arc-shaped plate 8 is fixed to the ladder body 6 by a rivet, and the positioning hole 9 is opened at the other end of the arc-shaped plate 8. The screw 10 can pass through the ladder body 6 and the positioning hole 9, and the nut 11 is adapted to the screw 10, so that the arc-shaped plate 8 can be fitted on the outside of the crossbeam 5 without falling off.

[0027] The bottommost crossbeam 5 is provided with a second clamp 12, which is fitted onto the bottommost crossbeam 5. The free end of the second clamp 12 is a C-shaped plastic plate, which can be fitted onto the crossbeam 5 on the opposite side. When not in use, the main ladder 1 and the auxiliary ladder 2 can be fixed together by the second clamp 12.

[0028] Based on the above embodiments, specifically, the main ladder 1 is provided with a handle 13 in the middle, and the handle 13 is fixed to the main ladder 1 by bolts, which can be easily held by hand.

[0029] Working principle: When dispensing annular flow obstruction particles, a ladder is first erected at the dispensing point. The main ladder 1 and the auxiliary ladder 2 are pulled apart from the bottom and opened to a suitable angle. Then, the shorter auxiliary ladder 3 is fixed to the two crossbeams 5 opposite to the main ladder 1 and the auxiliary ladder 2. At this time, the main ladder 1, the auxiliary ladder 2 and the auxiliary ladder 3 form an "A" shape structure. The upper triangular structure can maintain the stability of the device. When the pressure on the device is too great, another auxiliary ladder 3 is fixed between the two opposite crossbeams 5 to further improve the strength of the ladder. When the ground where the annular flow obstruction particles are to be dispensed is relatively soft, another auxiliary ladder 3 is fixed to the crossbeam 5 in the lower part of the main ladder 1. This auxiliary ladder 3 can increase the support surface of the device and improve the stability of use.

[0030] More specifically, a rubber sleeve 14 is provided in the middle of the crossbeam 5. The rubber sleeve 14 is fixed in the middle of the crossbeam 5. The upper middle part of the rubber sleeve 14 has a pattern, which can increase friction and further improve the safety of use.
