Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of power construction tools, and particularly relates to a falling object receiving device for 10kV distribution network live working high-altitude operation. BACKGROUND

[0002] At present, most of the 10kV distribution network live working needs to be cooperated with an insulated boom truck to transport the workers to the corresponding high-altitude operation position for operation. During the operation process, unexpected high-altitude falling objects may occur, for example, when performing the connection and lead line project, a part of the insulating sheath of the conductor needs to be peeled off. During the process of peeling off the insulating sheath of the conductor, there is a risk of accidental falling of the insulating sheath to hurt people. If it is a windy day, the falling point of the insulating sheath is not fixed under the blowing of the wind. For another example, when performing the connection and lead line project, the line, the lead line and the clamp need to be fixed and connected through bolts. During the process of screwing the bolts, there is a risk of high-altitude falling of the nuts or bolts. Moreover, the conductors in the high-altitude exist a difference or interlacing. Once the falling object contacts the two conductors during the falling process, a short circuit accident is easily caused.

[0003] At present, the main high-altitude power operation falling object prevention basically relies on the operation experience of the workers to avoid the occurrence of unexpected high-altitude falling objects in the process, or uses a simple net bag to receive the high-altitude falling objects. The worker stands in the insulated boom truck, and is limited by the outer edge of the insulated boom and the arm span of the worker himself, so that the worker cannot take the objects in the simple net bag. Moreover, the net bag itself has a certain height difference, and it is difficult to explore into the multiple conductors with a certain difference or interlacing. If a tent cloth with a certain elasticity is used to support the falling object, the falling object is easily up or deviated due to the irregular shape or falling contact point of the falling object, that is, the falling object falls into the elastic tent cloth and then pops out of the receiving range of the elastic tent cloth again.

[0028] The present application provides a falling object receiving device for 10kV distribution network live working high-altitude work, Figure 1 The present application provides a falling object receiving device for 10kV distribution network live working high-altitude work, Figure 1 The present application provides a falling object receiving device for 10kV distribution network live working high-altitude work, The two rod bodies 3 are arranged horizontally and spaced apart, the first ends of the two rod bodies 3 are connected to the fixed plate 1, the fixed plate 1 is arranged at the lower part of the lifting platform for manned high-altitude work, the second ends of the two rod bodies 3 extend horizontally to below the high-altitude power facility, and the second end sidewalls of the two rod bodies 3 are connected to the two sides of the hard lapping outer frame 4, axially limiting and vertically constraining the lapping hard lapping outer frame 4; The hard lapping outer frame 4 is of a rectangular structure, the hard lapping outer frame 4 comprises four sidewalls, each of the four sidewalls is provided with a plurality of hanging holes, each of the hanging holes is slidably sleeved with a hanging rope 6, the cloth bag 5 is located inside the hard lapping outer frame 4, the first ends of the plurality of hanging ropes 6 extend into the inner cavity of the hard lapping outer frame 4, the first ends of the hanging ropes 6 are fixedly hung at the open edge of the top sidewall of the cloth bag 5, the middle segments of the hanging ropes 6 slide through the hard lapping outer frame 4, and the second end portions of the hanging ropes 6 are fixedly hung with counterweight balls 10.

[0029] The top open edge of the cloth bag 5 is slidably hung with the hard lapping outer frame 4 through the plurality of uniformly distributed hanging ropes 6, the plurality of self-adapting sliding hanging ropes 6 and the counterweight balls 10 jointly resist the self-weights of the cloth bag 5 and the falling object and the falling kinetic energy of the falling object, and provide the cloth bag 5 with multi-stage downward buffering hanging force in the falling object receiving process and upward resetting force for avoiding the rebound of the falling object out of the cloth bag.

[0030] In actual use, the device of the present application is used to arrange the cloth bag 5 below the high-altitude power facilities through the rod body 3, effectively solving the problem that the existing net bag cannot be inserted between multiple wires due to the height difference; the hard lap outer frame 4 is used to normally hang and support the cloth bag 5 in a plane posture, and the falling object kinetic energy is absorbed by the downward movement and deformation potential of the cloth bag 5, which not only ensures the flexibility of the cloth bag 5, but also avoids the rebound problem caused by the irregular shape or falling contact point of the falling object, and provides multi-stage downward buffer hanging force when the falling object falls through the combined design with the hanging rope 6, effectively converting the kinetic / potential energy of the falling object, avoiding the rebound of the falling object out of the cloth bag 5; the stability of the hanging rope 6 is further enhanced by the setting of the counterweight ball 10, and the counterweight ball 10 provides the cloth bag 5 with the normal transverse tension of the cloth bag 5, consumes the kinetic energy of the falling object, and provides the tension for the cloth bag 5 to recover to the original position after receiving the falling object, avoiding the rebound of the cloth bag 5 when recovering to the original position, ensuring the stability of the process of receiving the falling object, and effectively solving the rebound problem of the falling object.

[0031] In the embodiment, the hanging rope 6 includes a first section extending to the inside of the hard lap outer frame 4 and a second section extending to the outside of the hard lap outer frame 4, the second section is sleeved with the buffer spring 9, and the end of the second section is fixedly hung with the counterweight ball 10, and the radius of the buffer spring 9 is smaller than the radius of the counterweight ball 10.

[0032] Through the added buffer spring 9, the kinetic energy of the rising of the counterweight ball 10 is converted into the elastic potential energy of the buffer spring 9 in the process of the falling object driving the cloth bag 5 to descend, the counterweight ball 10 rising, and the counterweight ball 10 extruding the buffer spring 9.

[0033] At the same time, the length of the buffer spring 9 is smaller than the length of the second section, and one end of the buffer spring 9 is connected to the side wall of the hard lap outer frame 4. In the initial state of the device of the present application, one end of the buffer spring 9 is fixedly connected to the outer wall of the hard lap outer frame 4, the middle section of the buffer spring 9 is bent downward with the hanging rope 6, and the other end of the buffer spring 9 is suspended and a predetermined interval is reserved between the other end of the buffer spring 9 and the counterweight ball 10, providing a self-weight interval for the upward movement of the counterweight ball 10, avoiding long-term operation of the buffer spring 9, and improving the service life of the buffer spring 9.

[0034] In addition, the rod body 3 in the embodiment adopts an electric telescopic rod, wherein the fixed plate 1 is fixedly arranged at the lower part of the lifting platform of manned high-altitude operation, one side of the fixed plate 1 is horizontally fixedly arranged with the fixed end of the electric telescopic rod, and the telescopic movable end of the electric telescopic rod is connected with the hard lap outer frame 4.

[0035] At the same time, the fixed plate 1 is fixedly arranged with the motor 2 providing axial telescopic power for the electric telescopic rod.

[0036] In addition, the second end of the rod body 3 is coaxially connected with the limiting disc 7, so that the axial displacement of the hard lap outer frame 4 is limited.

[0037] As shown in Figure 2 The hard lap outer frame 4 is preferably a vertically open rectangular frame structure, and three hanging holes are arranged at equal intervals on each of the four side walls of the hard lap outer frame 4. The hanging rope 6 is slidably penetrated in the hanging holes.

[0038] In addition, the cloth bag 5 includes a bag bottom and a side bag portion, and a top open structure is formed. The cross sections of the bag bottom and the side bag portion are rectangular structures, and the cross-sectional area of the side bag portion is smaller than that of the hard lap outer frame 4. The side wall of the side bag portion is hingedly connected to one end of the hanging rope 6.

[0039] Correspondingly, the depth of the cloth bag 5 should not be too deep, and the height of the side bag portion is 8-15 cm.

[0040] In this embodiment, the height of the side bag portion is 10 cm.

[0041] The two side walls of the hard lap outer frame 4 facing the rod body 3 are provided with a plurality of hooks 8 arranged downward. The hooks 8 are matched and hung on the circumferential outer wall of the rod body 3, so as to realize the hanging of the hard lap outer frame 4 and the rod body 3.

[0042] Correspondingly, the second end of the rod body 3 is coaxially connected with the limiting disc 7, so that the axial position of the limiting disc 7 is limited by the limiting disc 7.

[0043] In the present application, the buffer spring 9 and the counterweight ball 10 have a synergistic effect. One end of the buffer spring 9 is fixed to the hard lap outer frame 4, and the other end is telescopic with the self-adapting sliding hanging rope 6 to cooperate with the counterweight ball 10, forming a dynamic buffer system. This design not only effectively absorbs the impact force of the falling object, but also provides an upward reset force, completely solving the problem of rebound of the elastic tarpaulin.

[0044] In addition, the transmission connection mode of the motor 2 providing telescopic power for the electric telescopic rod meets the operation demand of stable position change of the cloth bag 5.

[0045] In order to increase the friction force between the hanging rope 6 and the hanging hole, the outer wall of the hanging rope 6 is provided with a granular pattern.

[0046] A 10kV distribution network live working high-altitude working falling object receiving device is provided by the present application, as shown in Figures 1 to 4 The device installation and working state of the present application are further described as follows: ​Before operation, personnel should install this device on the lower part of the lifting platform of the insulated bucket truck, and use high-strength bolts to firmly fix the fixing plate and the entire device horizontally to the preset installation position on the outside of the platform. When fixing, it is necessary to ensure that the extension direction of the rod 3 is horizontal, and that the entire device does not interfere with the normal lifting and lowering of the insulated bucket or the operating space of the operators.

[0047] After installation, start motor 2 to drive rod 3 to extend horizontally into the work area. The operator can precisely control the extension length of rod 3 according to the distribution of wires on site, so that the rigid overlapping frame 4 is accurately located directly below the risk point where objects may fall. Especially when performing short-circuiting or cutting operations on multiple wires with different heights, when operating on the upper wires, it is necessary to control rod 3 to extend horizontally between multiple wires.

[0048] At this point, the rigid overlapping outer frame 4 is stably attached to the circumferential outer wall of the second end of the rod 3 via multiple downward-facing hooks 8 symmetrically fixed at its top. The limiting disc 7 connected to the second end of the rod 3 effectively constrains the axial displacement of the rigid overlapping outer frame 4, ensuring its stability in the horizontal direction.

[0049] The cloth bag 5 is connected to the rigid overlapping outer frame 4 by multiple evenly distributed adaptive sliding hanging ropes 6; In the initial state, such as Figure 3 As shown, the cloth bag 5 is in an open position due to the weight of the counterweight balls 10. It is tensioned and kept in a near-horizontal position, slightly lower than the rigid overlapping outer frame 4, forming a stable receiving plane. This facilitates the receiving of falling objects and makes it convenient for workers to observe and grab the falling objects. It should be noted that the weight of the multiple counterweight balls 10 should be greater than the sum of the weight of the cloth bag and the falling object.

[0050] In the initial contact with the falling object, such as Figure 4 As shown, in the first stage, during the upward movement of the counterweight balls 10, the upward potential energy of the multiple counterweight balls 10 offsets the downward impact kinetic energy of the falling object; in the second stage, after the counterweight balls 10 contact the buffer spring 9, the deformation potential energy of the buffer spring 9 further absorbs the downward impact kinetic energy of the falling object, based on the first stage; in the third stage, the multiple counterweight balls 10 descend because their own weight is greater than the weight of the falling object and the weight of the cloth bag 5, thus driving the cloth bag 5 upward to the initial position of the first stage.

[0051] Furthermore, to describe the functions and collaborative working mechanisms of each component in this application, the following further explanation is provided: The fixing plate serves as the base of the entire device, and its core function is to securely install the device on the working platform of the insulated bucket truck and provide a stable reaction support point.

[0052] The rod body 3 and the motor 2, the core function is to realize the lateral accurate probe. The power is provided by the motor 2, drive the rod body 3 horizontal telescopic. So that the operating personnel need not risk a substantial probe out of the body, can be as the receiving device cloth bag 5 remote sent to the wire cross, gap complex dangerous area directly below, solve the existing technology in the net bag difficult to go deep into the problem. Its telescopic stroke can be adjusted according to the site situation, adaptability is extremely strong.

[0053] The limiting disc 7, the core function is axial constraint. For preventing the hard lap joint outer frame 4 in the device telescopic or by horizontal wind, accidental axial movement or rotation, ensure the accuracy of the operating position.

[0054] The hard lap joint outer frame 4, the core function is to provide a rigid, stable lap frame. It replaces the soft net bag of floating edge, through the connection of the hook 8 with the rod body 3, always form a reliable support plane. This ensures that the cloth bag 5 before, during and after receiving the falling object can maintain the expected posture, both convenient for receiving, also convenient for safe grabbing the falling object from the insulating bucket after the operation is completed, solve the problem of "can't get the simple net bag object".

[0055] The hanging rope 6 is the core innovation point of the application, the working mechanism is multi stage buffer and energy conversion, as follows: The hanging rope 6 is fixed to the cloth 5, the middle segment slides through the hard lap joint outer frame 4. Its core function is to guide the cloth bag 5 movement and provide multi stage buffer. When the falling object impacts the cloth bag 5, the hanging rope 6 can slide relative to the hard lap joint outer frame 4, through the friction force to preliminarily consume a part of the falling object kinetic energy.

[0056] Combined with the buffer spring 9, provide controllable elastic buffer and reset force. The buffer spring 9 first end is fixed to the outer wall of the hard lap joint outer frame, the middle segment is bent downward with the hanging rope, the second end of the buffer spring 9 is suspended. When the falling object impact causes the cloth bag 5 and the hanging rope 6 to move downward, will stretch and compress the buffer spring 9, so that it occurs greater deformation. The buffer spring 9 is compressed in the process, the falling object impact kinetic energy is converted into the elastic potential energy of the buffer spring 9, further weaken the kinetic energy of the falling object rebound upward.

[0057] The core function of the counterweight ball 10 is to provide inertia damping and limiting. It is fixed to the end of the hanging rope 6. When the cloth bag 5 falls rapidly, the inertia of the counterweight ball 10 will resist its movement, provide the effect similar to the damper, further consume the falling energy of the falling object. At the same time, it also interacts with the suspended end of the buffer spring 9, limit the downward amplitude of the cloth bag 5, prevent it from excessive swing.

[0058] The core function of the cloth bag 5 is to safely capture and contain the falling objects. In this embodiment, the preferred depth is 10 cm, which not only ensures sufficient containing space to prevent small items from bouncing out, but also avoids excessive depth that makes it difficult for the operator to retrieve the objects. Under the protection of the adaptive sliding rope system, it can smoothly accept the falling objects without bouncing violently.

[0059] In combination Figure 3 and Figure 4 , the detailed dynamic process of the working principle of the present application is as follows: Initial standby state: The cloth bag 5 is tensioned and maintained in the receiving preparation position under the pre-tightening force of the counterweight ball 10 and the self-weight.

[0060] The first stage, the initial attitude, as shown in Figure 3 : At this time, the cloth bag 5 does not contain falling objects, and the top open edge of the cloth bag 5 is subjected to the tension of the counterweight ball 10 on the hanging rope 6, showing the maximum degree of opening and the highest attitude in the vertical direction.

[0061] The second stage, the stage of receiving light falling objects, as shown in Figure 4 : When the falling objects such as nuts or insulating skins fall (the weight of the falling objects < the sum of the weights of the plurality of counterweight balls 10), the falling objects first impact the cloth bag 5, the impact force forces the cloth bag 5 to move downward, dragging the hanging rope 6 to slide and driving the plurality of counterweight balls 10 to move upward; during this process, the falling kinetic energy of the falling objects is converted into the upward potential energy of the counterweight balls 10, and the force calculation formula is: F = G + G 动能 = ng + n g势能 In the formula: G is the weight of the falling objects, G 动能 is the kinetic energy of the falling objects, n is the number of counterweight balls, g is the weight of the counterweight balls, g 动能 is the upward potential energy of the counterweight balls.

[0062] The third stage, the stage of receiving heavy falling objects, as shown in Figure 4 : When the falling objects such as hydraulic tongs and other tools (the weight of the falling objects > the sum of the weights of the plurality of counterweight balls 10), the counterweight balls 10 first perform the upward movement action of the second stage to preliminarily absorb the kinetic energy of the falling objects with the potential energy of the counterweight balls 10, and when the counterweight balls 10 contact the end of the buffer spring 9, the cloth bag 5 continues to move downward, at which time the counterweight balls 10 will compress the buffer spring 9, and the buffer spring 9 will generate elastic deformation potential energy by converting the remaining kinetic energy of the falling objects into the elastic deformation potential energy of the buffer spring 9, and the force calculation formula is: F = G + G 动能 = ng + n g势能 + mKS In the formula: m is the number of buffer springs, K is the spring constant of the buffer spring, S is the compression amount of the buffer spring.

[0063] The fourth stage is the recovery stage with the grabbing stage: When the kinetic energy of the falling object is completely converted into the deformation potential energy of the compression of the buffer spring 9 and the upward potential energy of the counterweight ball 10, the buffer spring 9 has a tendency to restore to its original state, and the counterweight ball 10 has a downward tendency driven by its own weight, thereby driving the cloth bag 5 to go upward, and further making the falling object slow up. In this process, the falling object will not bounce back immediately and quickly like stepping on a “trampoline”, but the process of releasing energy by the falling object is delayed and slowed down. This process ensures that there is not enough energy to make the falling object bounce significantly, thereby completely avoiding the risk of the falling object bouncing out of the cloth bag.

[0064] When the whole falling object receiving process is completed (when receiving a light falling object, stages one, two, and four are sequentially experienced; when receiving a heavy falling object, stages one, two, three, and four are sequentially experienced), the cloth bag 5 slowly rises under the action of the buffer spring and stabilizes at a new equilibrium position; wherein the counterweight ball 10 goes down to a steady state height, which is between the counterweight ball heights of Figure 3 and Figure 4 The working personnel can safely and conveniently take out the falling object in the cloth bag 5 from the insulated bucket. After the falling object is taken out, the device is automatically reset under the action of the buffer spring 9 and the counterweight ball 10, and is ready for the next receiving.

[0065] In addition, the heavy object receiving in the prior art mostly adopts spring buffering, air spring / liquid pressure buffering, sponge or cushion pad buffering, and the like, and the buffering principles are different from those of the present application, and the specific reasons are as follows: Among them, the buffering force calculation formula of the spring buffering, sponge or cushion pad buffering, and the like is: F = KS ; In the formula: K is the spring constant, S is the compression amount.

[0066] Among them, the buffering force calculation formula of the air spring / liquid pressure buffering is: F = Ps ; In the formula: P is the air / liquid pressure, s is the piston area.

[0067] It can be seen from the above two formulas that, under the condition that K is constant in the formula F=KS, the larger S is, the larger F is; similarly, under the condition that s is constant in the formula F=Ps, the larger P is, the larger F is, and the air spring / hydraulic buffer device is sealed, and the internal pressure P increases with the decrease of the volume of the rod cavity and the rodless cavity inside the air / liquid cylinder.

[0068] It is concluded that, whether it is a spring buffer, a sponge or a cushion, or a gas spring / hydraulic buffer device, the greater the compression, the greater the rebound force, and the greater the rebound force, the higher the risk of rebounding of the falling object.

[0069] The present application realizes the following core advantages through the above specific embodiments: Precise and in-depth: through electric telescopic, the receiving plane can be accurately sent to the dangerous area under the complex wire environment.

[0070] Effective buffering: through the multi-stage collaborative buffering mechanism of "sliding rope + buffer spring + counterweight ball", the falling object energy is efficiently converted and dissipated.

[0071] Reliable anti-rebound: through a controlled energy release process, the problem of rebounding and escaping of the falling object is fundamentally eliminated.

[0072] Safe and convenient operation: the operating personnel do not need to risk reaching in, and can complete all operations in the insulating bucket and easily retrieve the falling object.
