[0015] The application of the technical solution of the present invention has the following beneficial effects:

[0016] (1) The main cable anti-theft device of the construction elevator of the present invention comprises a protective rod and a protective cover group, wherein the protective cover group comprises two symmetrically arranged protective cover units, and the notches on the two protective cover units cooperate to form an opening allowing the protective rod to pass through; the main cable anti-theft device of the construction elevator of the present invention enables the cable to be completely sealed in the wire barrel through the cooperation of the protective cover group and the protective rod. When the hanging basket of the construction elevator is at the bottom position, the deadweight of the hanging basket applies pressure to the protective cover unit to close the entrance of the wire barrel by the protective cover unit. At the same time, the cable passes through the inside of the protective rod. Therefore, when the protective rod is extended into the inside of the wire barrel, the cable has no exposed part outside, which basically eliminates the risk of cable theft and increases the difficulty of stealing the cable.

[0017] (2) In the construction elevator main cable anti-theft device of the present invention, the shield unit is movably arranged on the wire drum through a connecting rod, and the two connecting rods are connected by a sleeve rod. The sleeve rod stabilizes the two connecting rods and increases the structural stability between the connecting rods and the sleeve rods.

[0018] (3) The anti-theft device for the main cable of the construction elevator of the present invention has an ingenious structure. The shield unit is connected to the wire drum by a spring. When the touch rod does not apply pressure to the shield unit, the shield group is opened by the elastic force of the spring (spring retracts), thereby realizing the normal working requirements of the construction elevator. When the touch rod applies pressure to the shield unit, the shield group can be closed (that is, when the touch rod applies pressure to the shield unit, the spring is in a stretched state and the shield group is closed; when the touch rod leaves the shield unit, the spring retracts and the shield group opens). When the construction elevator is in a non-working state, the pressure of the touch rod comes from the gravity of the hanging basket, and the shield group can be closed without the need for additional devices to provide pressure.

[0019] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0027] Embodiment 1:

[0028] See also Figure 1-4A main cable theft prevention device for a construction elevator comprises a protection rod 2 arranged on a hanging basket 1.1 and a shield group arranged on a wire drum 3, wherein the protection rod 2 is a hollow structure allowing the main cable to pass through from the inside, and the shield group is movably arranged on the wire drum 3 to realize opening or closing the entrance of the wire drum 3, and an opening is provided on the shield group to allow the protection rod 2 to pass through so that the protection rod 2 can extend into the interior of the wire drum 3, and a touch rod 2.2 is provided on the protection rod 2, and the shield group is opened or closed by touching the rod 2.2.

[0029] The hanging basket 1.1 is a component of the existing construction elevator 1. The specific structure of the construction elevator can be found in the prior art and will not be further described here.

[0030] The shield assembly includes two shield monomers 4 symmetrically arranged on the wire drum 3. The shield monomers 4 can be rotatably arranged on the wire drum 3. The shield monomers 4 are connected to the wire drum 3 through elastic members. The two shield monomers 4 are opened or closed by the cooperation of the touch rod 2.2 and the elastic member. When the touch rod applies pressure to the shield monomer, the elastic member is in a stretched state, and the two shield monomers are in a closed state. Figure 1 The two shield monomers are in a closed state; when the touch rod leaves the shield monomer, the elastic member retracts and the shield monomer is in an open state, see Figure 2 The two shield units are in the open state.

[0031] The shield unit 4 is arranged on the bobbin 3 through a connecting rod 6 , and the shield unit 4 is rotationally connected to the connecting rod 6 . The shield unit 4 and the connecting rod 6 are arranged one by one, and two connecting rods 6 are arranged in parallel and located on both sides of the bobbin 3 .

[0032] The same end of the two connecting rods 6 is connected by a sleeve rod 7, and the connecting rod 6 and the sleeve rod 4 are both arranged on the bobbin 3 through a U-shaped hook 3.2. The sleeve rod is an H-shaped structure, and through holes are provided at both ends of the sleeve rod, and the two connecting rods are respectively arranged through the through holes.

[0033] Preferably, a single shield unit 4 is provided with a notch, and the notches on the two shield units cooperate to form an opening for allowing the protective rod 2 to pass through. In this embodiment, the protective rod is a cylindrical structure, and the notch on the shield unit is a semicircular notch. When the two shield units are in a closed state, the two semicircular notches form a through hole for allowing the protective rod to pass through.

[0034] Preferably, the telescopic part is a spring 5, and a hook 3.1 is provided on the wire drum 3. The two ends of the spring 5 are respectively connected to the hook 3.1 and the shield unit 4. The spring and the shield unit can be connected by welding, or a hook can be provided on the shield unit to achieve the connection between the spring and the shield unit through the hook.

[0035] The protective rod 2 includes a first connecting section and an entry section which are arranged perpendicularly to each other, wherein the first connecting section is used to connect to the hanging basket 1.1, and the entry section is used to extend into the wire reel 3; the touch rod 2.2 includes a pressure section and a second connecting section which are arranged perpendicularly to each other, wherein the second connecting section is used to connect to the first connecting section of the protective rod 2, and the pressure section is used to apply pressure to the shield unit 4.

[0036] The protection bar 2 and the touch bar 2.2 are both L-shaped structures, and the protection bar 2 and the touch bar 2.2 are located on the same plane. The advantage of the protection bar and the touch bar being located on the same plane is that the protection bar will not interfere with the fixed structure of the cable on the construction elevator during the up and down movement.

[0037] The first connecting section of the protection rod 2 is provided with an ear plate 2.1, and the protection rod 2 is connected to the hanging basket 1.1 through the ear plate 2.1. The hanging basket 1.1 is provided with a cable through hole, and the first connecting section of the protection rod is inserted into the cable through hole, and the cable passes through the protection rod and the cable through hole to the hanging basket, and the ear plate and the hanging basket are connected by bolts.

[0038] The main cable anti-theft device for the construction elevator also includes a limit power-off device for the construction elevator. The limit power-off device for the construction elevator includes a touch switch 8 and a touch block 9. The touch switch 8 and the touch block 9 are respectively arranged on two shield monomers 4. The two shield monomers 4 are opened or closed to separate or contact the touch switch and the touch block. The purpose of setting the limit power-off device for the construction elevator is that when the two shield monomers are already in a closed state, the touch switch contacts the touch block, and the construction elevator is controlled by the touch switch to cut off the power supply, so as to prevent the construction elevator from continuing to move downward and causing damage to the anti-theft device. The touch switch can be a normally closed switch.

[0039] The technical solution of this embodiment is specifically:

[0040] The protection rod moves up and down on the construction elevator following the hanging basket, and the cable follows the movement of the hanging basket to be drawn out from the wire drum or put back into the wire drum;

[0041] During the operation of the hanging basket, that is, when the hanging basket moves upward, the touch rod moves upward along with the protection rod, the shield unit loses the pressure exerted by the touch rod, the shield group is retracted and opened by the spring (that is, the shield unit rotates), the entrance of the wire drum is opened, and the cable can be freely drawn out;

[0042] As the basket moves downward, the shield remains open and the cable is put back into the reel. When the touch rod applies pressure downward on the shield unit, the shield unit rotates under the pressure of the touch rod, thereby closing the entrance of the reel, and the entry section of the protective rod is inserted into the interior of the reel through the opening. When the basket stops at the bottom, the weight of the basket applies pressure to the shield unit to keep the cable enclosed in the reel when the construction elevator stops working, preventing theft.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
