Description

Technical field

[0001] The invention relates to a hoisting threading operating rod with convenient height adjustment, belonging to indoor hoisting auxiliary equipment. [Background Technology]

[0002] As people's living standards improve, electricity consumption is also increasing. In the industrial sector, various new large-scale equipment are being introduced into factories, leading to a continuous increase in electricity consumption. In the medical field, with the advancement of technology, various innovative large-scale medical devices are being introduced into surgical practice, increasing the electricity load of hospitals. As a result, the social demand for substations is becoming increasingly apparent, and the number of new substation projects is increasing. Currently, equipment failures caused by weather conditions have not been effectively resolved. In new substation projects, large equipment is installed indoors. Therefore, research on how to more conveniently and efficiently install equipment, conduct subsequent factory inspections, and expand indoor facilities has become a key focus of new substation projects. Currently, research on methods for hoisting large-scale equipment indoors has begun both domestically and internationally, and some progress has been made. However, relatively little research has been conducted on the threading process of hoisting equipment. Traditional manual threading is still the preferred method, which is inefficient, dangerous, and unsuitable for high-altitude work. Therefore, this paper studies a simple threading device to improve hoisting efficiency and facilitate workers in hoisting large-scale equipment indoors.

[0003] Currently, during substation electrical equipment installation, heavy equipment weighing 5 to 20 tons is primarily moved into place using capstans and rollers. This method requires a high level of worker experience and competence, and can cause extensive damage to the ground during movement. Therefore, overhead cranes are being introduced in new substation projects to facilitate the placement, maintenance, and installation of indoor equipment. While widely used and convenient, overhead cranes are time-consuming, labor-intensive, and expensive to install. Except in special circumstances, they are rarely used later, resulting in extremely low efficiency.

[0004] Therefore, for both efficiency and cost control, new substation projects no longer require overhead cranes. Instead, appropriate lifting points are installed in key locations. During the installation process, equipment is installed using these key lifting points. Indoor lifting is accomplished using lifting rings on the roof of the plant. These are typically U-shaped rings. A lead wire must first be threaded through the U-rings, and then the wire rope must be pulled through them. Therefore, how to easily and quickly thread the wire rope through the lifting rings is crucial to the entire lifting process. [Summary of the invention]

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a hoisting threading operating rod with convenient height adjustment, which can conveniently adjust the length of the operating rod and make each unit rod more versatile.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A lifting and threading operating rod with convenient height adjustment includes a rod body and a threading device located at the end of the rod body, the rod body is composed of at least two unit rods connected in a socket, each unit rod includes a main body section and a socket section, the outer diameter of the socket section is smaller than the outer diameter of the main body section, the top of the socket section is provided with an elastic pin extending radially to both sides, and the bottom of the main body section is provided with two symmetrically arranged docking holes. When the two unit rods are socketed with each other, the two docking holes of the main body section of one of the unit rods match the elastic pin of the socket section of the other unit rod, and the threading device is also provided with an insertion hole corresponding to the elastic pin.

[0008] The beneficial effects of the present invention are as follows:

[0009] First of all, the hoisting and threading operating rod in the present invention has a rod body composed of at least two unit rods connected in a socket manner, wherein each socketed rod includes a main body section and a socket section, and the outer diameter of the socket section is smaller than the outer diameter of the main body section. After such a design, a step surface will be formed between the socket section and the main body section, so that when the two unit rods are socketed with each other, the main body section of one of the unit rods can just be positioned against the step surface, thereby making the shaking of the two unit rods smaller. Because the hoisting height is usually high during hoisting, the height of the entire rod body is high, so the socketing stability requirements of the rod body itself are relatively high.

[0010] Secondly, the connection between the two unit rods in the present invention is achieved by matching and docking through radially arranged elastic pins. This structural design is first of all convenient during installation and disassembly. Secondly, the main thing is that the threading device at the end of the rod body in the present invention must be directional, which requires that the unit rods in the rod body cannot rotate relative to each other. Otherwise, when the user rotates the bottom of the rod body to adjust the orientation, the threading device at the top of the rod body is likely to not rotate with it, and the orientation adjustment function cannot be achieved. The use of the radial elastic pin structure can prevent relative rotation between the two mutually connected unit rods.

[0011] Finally, the threading device in the present invention is also provided with an insertion hole corresponding to the elastic pin. Such a design is equivalent to that each unit rod can be connected to the threading device. No matter how the height of the rod body is adjusted, using two unit rods, three unit rods, four unit rods, etc. will not affect the installation of the threading device. This can increase the versatility of each unit rod. Each unit rod can be connected to another unit rod, and can also be connected to the threading device, which greatly improves the degree of freedom.

[0012] Preferably, the socket section includes a first socket section and a second socket section, the outer diameter of the first socket section is smaller than the outer diameter of the second socket section to form a step, the threading device is socketed on the first socket section, and when the two unit rods are socketed with each other, the main section of one unit rod is socketed on the second socket section of the other unit rod.

[0013] Preferably, a positioning friction member is provided on the outer wall of the second sleeve section.

[0014] Preferably, the positioning friction member comprises multiple pieces, which are circumferentially distributed on the outer wall of the second sleeve section.

[0015] Preferably, the positioning friction plate is a plastic sleeve sleeved on the second sleeve section.

[0016] Preferably, among the at least two unit rods, the length of at least one unit rod is shorter than the lengths of the other unit rods.

[0017] Preferably, the hoisting and threading operating rod further includes a wire winding drum, which is installed on the main section of the unit rod, and the wire winding drum and the main section of the unit rod are detachably connected.

[0018] Preferably, the winding drum is connected to the main body section via a clamp, and the main body section is provided with an annular groove for positioning the clamp.

[0019] Preferably, the winding drum comprises a sleeve, a rotating shaft and a wire drum connected to the rotating shaft, and a brake device for braking the rotating shaft is installed on the sleeve.

[0020] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0027] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0028] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0029] Example 1:

[0030] like Figures 1 to 5 As shown, this embodiment shows a threading operating rod for hoisting, including a rod body and a threading device 2 located at the end of the rod body, the rod body is composed of at least two unit rods 1 connected in a socket, each unit rod 1 includes a main section 11 and a socket section 12, the outer diameter of the socket section 12 is smaller than the outer diameter of the main section 11, the top of the socket section 12 is provided with an elastic pin 13 extending radially to both sides, and the bottom of the main section 11 is provided with two symmetrically arranged docking holes 14. When the two unit rods 1 are socketed with each other, the two docking holes 14 of the main section 11 of one unit rod 1 match the elastic pin 13 of the other unit socket section 12, and the threading device 2 is also provided with an insertion hole 26 corresponding to the elastic pin 13.

[0031] The beneficial effects of the present invention are as follows:

[0032] First of all, the hoisting and threading operating rod in this embodiment has a rod body composed of at least two unit rods 1 connected in a socketed manner, wherein each socketed rod includes a main body section 11 and a socket section 12, and the outer diameter of the socket section 12 is smaller than the outer diameter of the main body section 11. After such a design, a step surface will be formed between the socket section 12 and the main body section 11, so that when the two unit rods 1 are socketed with each other, the main body section 11 of one of the unit rods 1 can just be positioned against the step surface, thereby making the shaking of the two unit rods 1 smaller. Because the hoisting height is usually high during hoisting, the height of the entire rod body is high, so the socketing stability requirements of the rod body itself are relatively high.

[0033] Secondly, in this embodiment, the connection between the two unit rods 1 is achieved by matching and docking through radially arranged elastic pins 13. This structural design is firstly convenient during installation and disassembly. Secondly, the main thing is that the threading device 2 at the end of the rod body in the present invention must be directional, which requires that the unit rods 1 in the rod body cannot rotate relative to each other. Otherwise, when the user rotates the bottom of the rod body to adjust the orientation, the threading device 2 at the top of the rod body is likely to not rotate with it, and the orientation adjustment function cannot be achieved. The structure of the radial elastic pin 13 can prevent the two mutually connected unit rods 1 from rotating relative to each other.

[0034] Finally, the threading device 2 in this embodiment is also provided with an insertion hole 26 corresponding to the elastic pin 13. Such a design is equivalent to that each unit rod 1 can be connected to the threading device 2. No matter how the height of the rod body is adjusted, using two unit rods, three unit rods, four unit rods, etc. will not affect the installation of the threading device 2. This can increase the versatility of each unit rod 1. Each unit rod 1 can be connected to another unit rod 1, and can also be connected to the threading device 2, which greatly improves the degree of freedom.

[0035] In order to make the unit rod 1 and the threading device 2 more stable when they are socketed, the socket section 12 includes a first socket section 121 and a second socket section 122. The outer diameter of the first socket section 121 is smaller than the outer diameter of the second socket section 122 to form a step. The threading device 2 is socketed on the first socket section 121. When the two unit rods 1 are socketed with each other, the main section 11 of one unit rod 1 is socketed on the second socket section 122 of the other unit rod 1.

[0036] Since the unit rod 1 itself is usually made of a metal rod, and friction is easily generated between metal and metal, there will be a certain gap between the unit rods 1 and the unit rods 1 after long-term disassembly and assembly, which will cause the two unit rods 1 to shake after being socketed, thereby causing the threading device 2 on the top of the rod body to have poor stability and not be easy to align with the hanging ring. In order to solve this technical problem, a detachable positioning friction part 15 is provided on the outer wall of the second socket section 122. The positioning friction part 15 is preferably made of plastic. After the positioning friction part 15 is set, it can be ensured that the fit between the two unit rods 1 is an interference fit, thereby improving stability. At the same time, even if wear occurs, the wear area is concentrated on the positioning friction part 15, which can be removed and replaced later.

[0037] In this embodiment, the positioning friction member 15 is preferably in the form of a sheet, with multiple pieces distributed circumferentially on the outer wall of the second sleeve section 122. This type of positioning friction member 15 offers the advantages of easy installation and easy replacement based on wear. For example, if one side is severely worn, the more worn side can be replaced. Of course, in other embodiments, the positioning friction member 15 can also be a plastic sleeve mounted on the second sleeve section 122. This type of plastic sleeve positioning friction member 15 offers the advantage of greater stability.

[0038] Since the heights of many indoor hoisting rings are not the same, in order to make the height of the threading operating rod relatively suitable for the hoisting ring, among the at least two unit rods 1 described in this embodiment, at least one unit rod 1 is shorter than the lengths of the other unit rods 1. This design is equivalent to having several unit rods 1 with different lengths among the multiple unit rods 1, which allows users to combine and splice them into a more suitable height.

[0039] The hoisting and threading operating rod further includes a wire reel 323, which is mounted on the main section 11 of the unit rod 1. The wire reel 323 and the main section 11 of the unit rod 1 are detachably connected. With this design, the wire reel 323 can be carried and moved independently, making transportation more convenient.

[0040] The winding drum 323 is connected to the main section 11 via a clamp 31. The main section 11 is provided with an annular groove 111 for positioning the clamp 31. The annular groove 111 can be provided on each unit rod or only on a certain unit rod 1. In this embodiment, it is preferred that the annular groove 111 be provided on only one unit rod 1, because the winding drum 323 is usually fixedly mounted on only one unit rod 1.

[0041] In this embodiment, the winding drum 323 includes a sleeve, a rotating shaft, and a wire drum 32 connected to the rotating shaft. The rotating shaft can rotate within the sleeve, which is fixed to the clamp 31. The sleeve is mounted with a brake device for braking the rotating shaft. In this embodiment, the brake device can be a hand crank. Braking is achieved by holding the hand crank to prevent the counterweight 21 from falling too quickly and hitting objects or people. In other embodiments, the brake device can also be implemented using some clamping mechanism.

[0042] Regarding the structure of the threading device 2, in this embodiment, the threading device 2 includes a counterweight 21, a piston rod 22 and a transmission rod 23. The end of the threading is connected to the counterweight 21. The piston rod 22 includes a locking end and a connecting end. The locking end is used to lock or release the counterweight 21, and the connecting end is used to be hinged to the transmission rod 23. The other end of the transmission rod 23 is rotatably connected to the drive shaft 24. The drive shaft 24 is connected to a force plate 25. The force plate 25 presses against the lifting ring upward or downward to form a force to drive the drive shaft 24.

[0043] The specific operating principle of the threading operating rod in this embodiment is to connect one end of the threading in the winding reel 323 to the counterweight 21 in the threading device 2, and the counterweight 21 follows the threading operating rod to the height position of the hanging ring, and then allows the counterweight 21 to pass through the hanging ring. After the counterweight 21 passes through the hanging ring, the counterweight 21 is released, allowing the counterweight 21 to fall freely. In this way, the user can stand on the ground to realize the operation of threading the wire around the hanging ring without using equipment such as a ladder. It is very convenient to operate, and the entire equipment is very portable to move and carry.

[0044] Secondly, the release of the counterweight 21 in this embodiment is basically achieved through a purely mechanical structure, and does not require any other power source. When in use, it is only necessary to align the force plate 25 with the lifting ring and squeeze it. The force plate 25 will transmit the force to the drive shaft 24, so that the drive shaft 24 drives the piston rod 22 to perform the release operation. The entire internal structure is very simple and does not require components such as motors and power supplies. It is not only low-cost, but also does not require power access, has low requirements on the working environment, and has a wide range of applications.

[0045] Regarding the specific structure of the threading device 2:

[0046] The threading device 2 includes a shell, which includes a counterweight cavity and a piston cavity that are interconnected. The counterweight 21 is at least partially located in the counterweight cavity, and the piston rod 22 is located in the piston cavity. The piston rod 22 can reciprocate in the piston cavity. In the locked state, the piston rod 22 at least partially extends into the counterweight cavity and locks with the counterweight 21. In the released state, the end of the piston rod 22 will exit the counterweight cavity, thereby unlocking the counterweight 21.

[0047] The housing also includes a drive shaft cavity, and the drive shaft 24 is located in the drive shaft cavity. Regarding the specific orientation of the several chambers, the piston cavity in this embodiment is horizontally arranged, and the drive shaft cavity and the counterweight cavity are both vertically arranged. The force plate 25 is mounted below the drive shaft 24. For details, please refer to Figure 5 As shown in the figure, since the axial direction of the hole of the hanging ring is usually horizontal, when the counterweight block 21 passes through the hole of the hanging ring, the force plate 25 can be located in the middle of the hanging ring. At this time, the user pulls the threading device 2 downward with force, which will make the force plate 25 contact the inner wall of the hole of the hanging ring, and push the force plate 25 to move upward. After the force plate 25 moves upward, it will also move upward synchronously with the drive shaft 24, thereby driving the piston rod 22 to move to the right to complete the release action. This orientation design is very suitable for the working environment of the hanging ring, and the force plate 25 is normally hung below the drive shaft 24. When there is no force, the force plate 25 will rely on its own weight to keep the piston rod 22 in the locked position.

[0048] In order to prevent the self-weight of the force plate 25 from being insufficient, a return spring 27 is further provided between the top of the drive shaft 24 and the inner wall of the drive shaft cavity in this embodiment to increase the return capability of the drive shaft 24 .

[0049] In order to facilitate locking with the piston rod 22, the counterweight 21 in this embodiment is provided with a locking groove 211, and the end of the piston rod 22 extends into the locking groove 211 to lock the counterweight 21. In this embodiment, the counterweight 21 includes a main body 212 and a mounting portion 213. After the main body 212 and the mounting portion 213 are provided, the main weight of the counterweight 21 can be concentrated on the main body 212, and the main body 212 can be exposed outside the shell, thereby reducing the volume of the shell itself. The mounting portion 213 is a cylindrical structure, and the mounting portion 213 is accommodated in the counterweight cavity. The locking groove 211 is an annular groove provided on the mounting portion 213. The advantage of designing the locking groove 211 as an annular groove is that the annular groove can be docked and locked with the piston rod 22 at any angle, without the need for a specific installation angle. Therefore, when the counterweight 21 is installed, it can be inserted into the counterweight cavity at any angle.

[0050] Considering that different hoisting and threading operations may require different counterweights 21, the housing in this embodiment includes a main housing 202 and a front housing 201 connected to the end of the main housing 202, and the counterweight cavity is located within the front housing 201. This allows the front housing 201 to be a separate component and can be replaced without replacing the main housing 202. The piston rod 22, transmission rod 23, drive rod, and other structures within the main housing 202 can be interchangeable.

[0051] In addition, since the threading device 2 is usually at a higher position and the user is standing on the ground, considering that there is an alignment problem when the user aligns the threading device 2 with the hole of the hanging ring, it is preferred to set a guide portion at the front end of the front shell 201. The guide portion can be a cone with a relatively small front end, which can easily enter the hole of the hanging ring. Of course, in other embodiments, it is also preferred to install a camera at the front end of the front shell 201. The camera is connected to a wireless transmission module that transmits image signals to the user's mobile terminal. In this way, the user can more accurately align the hole of the hanging ring based on the image signal transmitted by the camera on the ground.

[0052] In addition, the shell also includes a rear shell 203 connected to the other end of the main shell 202. The rear shell 203 is used to connect to the shaft. This is to take into account the fact that the thickness of the shaft may not be uniform. For example, some shafts are 6 cm round tubes, while some may be 8 cm round tubes. In this case, only the rear shell 203 needs to be replaced, and the main shell 202 and the front shell 201 can be used universally.

[0053] In the specific assembly, since there are piston chambers and drive shaft chambers in the main shell 202, these chambers need to install parts, so the main shell 202 includes a left half shell 2021 and a right half shell 2022, and the left half shell 2021 and the right half shell 2022 are spliced ​​and connected, so that the piston rod 22 and the drive shaft 24 can be easily assembled. After the left half shell 2021 and the right half shell 2022 are fully installed, they are fastened with screws. At the same time, after the left half shell 2021 and the right half shell 2022 are spliced, they are connected as a whole with the front shell 201 and the rear shell 203, which is equivalent to the front shell 201 and the rear shell 203 also playing a fixed connection role for the left half shell 2021 and the right half shell 2022, further enhancing the connection stability between the left half shell 2021 and the right half shell 2022.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the drawings and the above specific embodiments.
