Description

Technical Field

[0001] The invention relates to the field of building engineering construction, and in particular to a telescopic device and method for preventing pouring to a track plane. Background Art

[0002] In projects involving the pouring of gantry crane track beams or the reinforcement of factory floor, due to the small or remote working surface of the pouring site, more or less concrete will drip onto the steel plate during the pouring process. The installed steel plate will be poured with concrete, but the surface of the steel plate needs to be kept clean and tidy. It is time-consuming and laborious to clean up the dripping concrete after it dries, posing a serious threat to construction management cost control.

[0003] At present, there are two common treatment measures for this phenomenon: one is to purchase a matching concrete pouring funnel, and the other is to manually remove it after direct pouring. Since some construction sites are far away from the city and are relatively remote, purchasing a matching pouring funnel takes a long time, is expensive, and has few opportunities for reuse, which is not conducive to cost control. Manual removal after direct pouring will increase the labor cost and construction time, which has an adverse impact on construction management cost control. Therefore, it is urgent to find a portable tool to solve this problem. Summary of the invention

[0004] In order to solve the technical problems existing in the prior art, the present invention provides a telescopic device and method for preventing pouring to the track plane.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] A telescopic device that is anti-cast to the track plane includes a hard sheet, a spring, a locking bead, a hole and a locking bead track. The locking bead is slidably connected to the locking bead track. When the locking bead moves to the hole, the spring is stretched to make the locking bead clamp the hole, so that the device is fixed and the device can be extended or contracted forward, backward, left and right.

[0007] When a thrust is applied to the hard sheet, the locking ball moves along the inner wall of the locking ball track.

[0008] A plurality of telescopic devices are arranged on one track plane.

[0009] The hard sheet is made of non-adhesive hard material.

[0010] A method for using a telescopic device for preventing pouring to a track plane comprises the following steps:

[0011] Step 1: Apply an inward thrust to the lock ball to compress the spring;

[0012] Step 2, applying an outward thrust to the hard sheet to move the locking bead along the locking bead track on the inner wall;

[0013] Step 3: When the locking bead moves to the hole at the desired position, stop applying the thrust, so that the locking bead stretches through the spring and blocks the hole, so that the device is fixed;

[0014] Step 4: When the device needs to be extended or retracted, repeat the above steps. When the working surface to be protected is large, multiple devices can be used to operate simultaneously.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The telescopic device of the invention, which is anti-casting to the track plane, cleverly utilizes the principle of the telescopic rod of an umbrella, so that it can be extended or contracted forward, backward, left, and right. After the telescopic device is installed, the locking bead slides along the locking bead track through artificial lateral and longitudinal forces, and the locking bead fixing device pops out through the spring when it reaches the hole at the required position, thereby realizing the extension and contraction forward, backward, left, and right.

[0017] The telescopic device is convenient and quick to extend and retract, without additional labor costs. When the anti-casting area is large, multiple sets of telescopic devices can be arranged to operate simultaneously. It should be noted that the hard sheet of the telescopic device must be made of non-adhesive hard material, which is convenient for recycling, cleaning and reuse after construction. If it is considered to be disposable, ordinary hard sheets can also be used. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solution of the present invention is further described below in conjunction with specific implementation methods:

[0024] like Figure 1As shown, a telescopic device that is anti-casting to the track plane includes a hard sheet 1, a spring 2, a locking bead 3, a hole 4 and a locking bead track 5. The locking bead 3 is slidably connected to the locking bead track 5. When the locking bead 3 moves to the hole 4, the spring 2 is stretched to make the locking bead 3 clamp the hole 4, so that the device is fixed, thereby realizing the extension or contraction of the device forward, backward, left and right.

[0025] When a thrust is applied to the hard slice 1 , the locking ball 3 moves along the inner wall of the locking ball track 5 .

[0026] The hard sheet 1 is made of non-adhesive hard material.

[0027] The method of using the device is as follows: applying an inward thrust to the locking ball 33 to compress the spring 22;

[0028] Then, an outward thrust is applied to the hard sheet 1, so that the locking ball 3 moves along the inner wall locking ball track 5;

[0029] When the locking bead 3 moves to the hole 4 at the desired position, stop applying the thrust, so that the locking bead 3 stretches through the spring 2 and clamps the hole 4, so that the device is fixed;

[0030] It is necessary to extend one section or retract the device and repeat the above steps. When the working surface to be protected is large, multiple devices can be used to operate simultaneously.

[0031] This embodiment is only a further explanation of the invention rather than a limitation of the invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of the claims of the invention, they are protected by the patent law.
