Description

[Detailed explanation of the invention] (Purpose of the invention) This invention is a rope that is used to quickly, easily, and safely clean mortar, etc. that has adhered to the form shell after concrete is poured into mobile formwork for tunnels. Regarding the type Keren device.

(Prior art) Conventionally, cleaning the outer circumferential surface of mobile formwork for tunnels after concrete was poured was done manually by sprinkling water and scrubbing with a brush, but this method was extremely difficult due to the narrow space. Not only was this inefficient, it was also unsanitary and dangerous. In addition, there were some models in which the rotating brush rotated back and forth on the outer peripheral surface along a guide rail, but the structure was complicated and the cost was high.

(Structure of the invention) In order to eliminate the above-mentioned problems, this invention has a large number of sheave groups attached to each of the traveling trolleys, which are attached to the inner sides of the movable formwork so as to be freely driven and run in the longitudinal direction. An endless rope wrapped around a group of sheaves is straddled by contacting the outer peripheral surface of the form, and the group of sheaves on one side can be freely driven and rotated by a drive device.

This invention will be explained based on the diagram of the example.
As shown in FIGS. 1 to 4, the rope-type cleaning device 1 is installed at the lower ends of side forms 4 on both sides of a movable formwork 3 that is movable in the longitudinal direction on rails 2 laid on a floor F of a tunnel T. A trolley rail 6 is installed in parallel to a plurality of arms 5 which are protruded inwardly in the vicinity in a substantially horizontal direction, and a traveling trolley 9 having wheels 7 and a motor 8 that rolls within the trolley rail 6 is installed. Fitted respectively, same speed,
They can run freely in the same direction.

Post 1 suspended and fixed to this traveling trolley 9
A plurality of sets of 11 groups of sheaves of the same diameter are freely rotatably attached to the 0, along with corresponding 12 groups of guide rollers, and fixed to one of the 11 groups of sheaves on either side of the 11 groups on either side. rotating shaft 13
and a drive device 16 having a drive motor 15 disposed on a mounting base 14 attached to the lower part of the pillar 10, and an endless rope 17 for cleaning is connected to the groups of sheaves 11 on both sides of the movable formwork 1. Outer peripheral surface 19 of form 4 and atsupah form 18
Place it in contact with the material, straddle it, and wrap it.

In the figure, 20 is a mounting trolley for the movable formwork 1, 21 is a bar jack, 22 is an attachment part of the bar jack 21 on the trolley side, 23 is an attachment part on the side form side of the same, 24
25 indicates the wheels of the mounting truck, 25 indicates the peeling ring, and W indicates the concrete wall.

(Function of the device) The function of the device will be explained based on the drawings of the embodiment. As shown in FIGS. 1 to 4, once concrete placement is completed in the tunnel T, , the outer peripheral surface 1 of the concrete wall W, the side form 4 and the top form 18
9 is released, the side form 4 is moved inward using a rod jack 21 or the like, and at the same time the upper form 18 is also jacked (not shown).
A slight gap W is provided between the concrete wall W and the outer peripheral surface 19 of the form.

Next, the drive device 1 attached to the sheave group 11 on one side
6 is activated, the rotating shaft 13 fixed to one sheave 11 is directly connected to the drive device 16, so the sheave 11 attached to this rotating shaft 13 starts driving rotation. As shown in Figures 5 and 6,
Since the endless rope 17 is guided and wound around the guide rollers 12 groups corresponding to the sheaves 11 groups on both sides, the endless rope 17 starts rotating in the direction shown by arrow R, and this endless rope 17 Since the endless rope 17 contacts and straddles the outer circumferential surfaces 19 of the form 4 and the upper form 18, the endless rope 17 rotates while sliding on the outer circumferential surfaces 19. At this time, when the running trolleys 9 on both sides are run in the same direction and at the same speed in the longitudinal direction by the drive of the motor 8, the endless rope 17 rubs the outer peripheral surface 19 in the circumferential direction and also in the longitudinal direction. Since it moves while moving, it will rub over the entire outer circumferential surface 19, and dirt such as mortar stuck to the outer circumferential surface 19 of the foam will be completely rubbed off, making cleaning within the narrow gap K easy and quick. . If cleaning after one reciprocation is still insufficient, the traveling trolley 9 may be reciprocated many times.

(Effects of the invention) Since this invention has the above structure, it has the following advantages.

(1) Since it is rubbed with a rope, even narrow gaps can be easily cleaned.

(2) Since the structure is simple, the cost of the device can be extremely reduced.

(3) Fully automatic, allowing for quick, safe, and efficient work.
