Description

[Detailed description of the invention] Industrial field of application The present invention relates to a mobile cart for a cutter or cutter, which is particularly tall compared to its width and easily falls over, so that the cutter can be easily moved by pulling it out from a switchboard. It is related to a mobile trolley that can move.

BACKGROUND TECHNOLOGY There are the following methods for storing a disconnector in a power distribution board, or for pulling out a stored disconnector from a power distribution board and moving it to another location. In other words, (a) a method in which the shiyashita cutter itself is moved directly on the floor using its own wheels; (b) A method in which the shear cutter is placed on a moving trolley and moved using the wheels of the trolley.

Therefore, among the methods (a) and (b) above, method (b), which uses the mobile trolley made exclusively with the convenience of transport in mind, is superior in terms of ease of movement. , method (b) is generally adopted.

Next, an example of method (b) will be explained based on FIG. 10.

22 is a conventional mobile cart, and 12 is a fork-shaped loading platform 7 that carries a load cutter. The loading platform 7 is provided so that it can be moved up and down along the pillar 1 rising from the underframe 2. Reference numeral 6 denotes a winding operation device provided on the pillar 1, which has a drum in its case for winding up the wire rope 9. 11 is a handle for operation. After the wire rope 9 is pulled out from the hoisting operation device 6, it is further pulled down via a pulley 16 provided at the top of the column 1, and its tip is connected to the platform 7 via the platform receiving frame 8. Therefore,
By operating the handle 11, the loading platform 7 can be moved up and down along the pillar 1. 3 is a fixed wheel provided on the underframe 2, and 4 is a movable wheel.

To place the sheath cutter 12 on the movable cart 22, the handle 11 is operated to lower the cargo platform 7 to the floor level, place the sheath cutter 12 on it, and then raise the cargo platform 7 a little again. As shown in the figure, the wheels 23 of the sheath disconnector 12 are moved by the fixed wheels 3 and movable wheels 4 of the movable cart 22 without coming into contact with the floor.

By the way, in recent years, the size of the circuit breaker has progressed, and the width dimension of the switchboard that houses it has also progressed. However, due to the demand for further downsizing of switchboards, especially reduction in panel width, as shown in FIGS. 6 and 7, the width dimension of the shield breaker 12 has become smaller, while the height dimension h has become larger. There is a tendency.

Problems to be Solved by the Invention When storing the disconnector 12 in the switchboard as shown in Figures 6 and 7, or when pulling it out and moving it to another location, the width is small and the height is large. Whether the mustard cutter 12 is moved directly on the floor or moved on the moving cart 22, it is extremely unstable and dangerous. Furthermore, the work of loading and unloading the vehicle onto the mobile cart 22 is very time-consuming. Therefore,
Conventionally, in either method (a) or (b) above, it was dangerous to move the disconnector 12 by one person, and an additional assistant was required during the movement, resulting in poor work efficiency. . Therefore, the present invention aims to provide a moving cart that allows the shield disconnector to be moved directly on the floor safely and easily, without requiring an assistant, when the disconnect switch is taken in and out of the switchboard. It is something.

Means and operation for solving the problems The present invention solves the above problems.
In other words, the movable trolley for shear breakers according to the present invention is as follows:
It has an underframe to which wheels are attached, a support that rises from the underframe, and arm members that extend backward from the support.
These underframes and arm members are arranged along both sides of the chopper and cutter, and the movable cart also has a hook for pulling out the cutter and cutter, which can be moved back and forth by operating the handle. The device is characterized in that a drawer link mechanism is provided, and the movable trolley is approached from the front of the shingle disconnector, and by operating the drawer link mechanism, the switchboard can be pulled out. The structure is such that it can be integrally connected to a movable cart as it is, so that the sheath cutter can be easily moved directly on the floor together with the cart.

EXAMPLE The present invention will be explained in detail below with reference to FIGS. 1 to 9.

First, in FIGS. 8 and 9, 25 is a moving cart according to the present invention, and 26 is an underframe to which wheels 3, 3 are attached. The underframe 26 has a substantially U-shape when viewed from above, and the front ends of both side frames 26a and 26a are connected by a horizontal frame 26b. And both side frames 26
₁ of a and 26a are provided to such an extent that they can be entered along both sides of the lower end of the sheath cutter 12. Both sides frame 2
A gate-shaped support 1 stands up from 6a and 26a when viewed from the front, and a handle 14 for moving the cart is provided in front of the support 1 via a connecting rod 27.
The structure including these struts 1 and handles 14 is the same as that of a conventional mobile cart 22.

A pull-out link mechanism 28 is provided on the support column 1, and the pull-out link mechanism 28 can pull out the scissors and cutter 12 and connect it to the movable cart 25, the detailed structure of which is shown in FIG. That is, a guide rail 13 as an example of an arm member is integrally provided rearward from the support 1, and the guide rail 13
A drawer link mechanism 28 is installed in the guide groove 20 provided in the
Both ends of a movable rod 30, which constitutes one member of the rod 30, are slidably fitted together. The drawer link mechanism 28 is

The first parallel link 17 and the second parallel link 32 and the first and second parallel links 17, 3 that connect the
The left and right connecting rods 33 connect the left and right sides of the two. A hook 21 is provided on the movable rod 30, and a handle 18 is fixed to one end of the support rod 31. Note that the guide rail 13 as an arm member is provided at a predetermined height position from the underframe 26, and has the role of holding both ends of the sheath cutter 12 together with the underframe 26 to prevent the sheath cutter from tilting. fulfill.

Next, the sheath cutter 12 is moved by the moving cart 25.
The drawing operation will be explained with reference to FIGS. 1 to 3 and FIGS. 5A and 5B. First, the movable cart 25 is approached from the front of the sheath cutter 12. At this time, the drawer link mechanism 28 has its first and second parallel links 1
7 and 32 are in a linearly extended state, and in this state, the hook 21 is hooked on the manual drawer handle 19 of the sheath cutter 12.

At this time, the handle 18 is standing vertically, so next, hold the handle 18 by hand and turn it counterclockwise. Then, as shown in FIGS. 5A and 5B, the distal end side of the second parallel link 32 integrated with the support rod 31, that is, the left and right connecting rod 33, is lifted, so one end of the first parallel link 17 is also lifted, and the movable rod is accordingly lifted. 3
0 also moves to the front side, and the handle 18 and drawer link 29 operate in the order shown in FIG. They are integrally connected in a state where they are connected. Figure 1 shows the state of the ladder and disconnector 12 before it is pulled out.
FIGS. 2 and 3 show the state after the drawer is completed. Also, at this time, the shield breaker 12 and the moving trolley 2
The positional relationship between the wheels 23 and 3 of No. 5 is also shown in each of the above figures. Note that 15 is a truck stopper provided at the rear end of the underframe 26;
5 may be omitted depending on the panel structure of the switchgear.

Effects of the Embodiment According to the embodiment described above, the operation for pulling out the sheath cutter 12 is performed after the hook 21 of the movable cart 25 engages with the drawer handle 19 of the sheath cutter.
This can be done by performing the operation in step 8, and after pulling it out, it will be in the state shown in Fig. 5A and E, which also means that the cable disconnector 12 has been connected to the moving cart 25, so it will not be in this state. A trolley 25 that moves the disconnector 12
can be moved together.

In addition, the manner in which the wheels touch the ground after the sheath breaker 12 is pulled out is such that the width of the movable cart 25 and the length after the movable cart 25 and the shim breaker 12 are connected together are substantially the same as that of the sheath breaker 12. It has a width and a length that is larger than the length of the cutter alone, so that it can be moved stably. Furthermore, in order to increase the stability of the sheath cutter 12 in the height direction, the underframe 26 and guide rails 13 that hold both sides of the sheath cutter 12 effectively serve as supports. In addition, contact with the floor surface is caused by moving trolley 2.
Since there are 8 wheels in total, 4 wheels 3 of No. 5 and 4 wheels 23 of shear cutter 12, stability is increased from this point as well. Therefore, even if the floor surface is somewhat uneven, it can be moved relatively stably.

Furthermore, when pulling out the sheath cutter 12 from the board 24, the hook 21 is pulled forward horizontally to the board surface along the guide rail 13 of the movable cart 25. No vibration,
You can perform reliable drawer work. In addition, Shiya disconnector 1
2 can be inserted in the same way as when pulled out.

Effects of the invention As described above, according to the present invention, by approaching the shaya breaker from the front with a movable trolley and operating the pull-out link mechanism provided on the movable trolley, the shaya breaker can be moved from the power distribution board. The movable cart can be pulled out from the drawer, and the movable trolley and the shear cutter can be integrally connected and moved to the designated location. Work can be done easily and efficiently.
