[0002] At present, construction hoists are a common and indispensable mechanical equipment in the construction stage. It is mainly used to transport personnel, materials and equipment in high-rise building construction, and is an important means of realizing vertical transportation. Construction hoists usually use steel wire ropes installed in the shaft to lift and position the lifting platform. However, steel wire ropes are easily affected by various external factors during long-term use, such as wear, corrosion, and complex stress environments, which reduces the safety and service life of steel wire ropes. In the actual construction process, the breakage or wear of steel wire ropes will bring serious safety hazards and economic losses to construction personnel and the overall progress of the project.

The transmission rod rotates, thereby driving the pressure block to tightly press the wire rope in the wire rope guide groove. This instant response mechanism greatly enhances safety protection and ensures that in the event of an accidental wire rope breakage, measures can be taken quickly to avoid further safety accidents.

[0046] In addition, the wire rope contact surface of the pressure block adopts a serrated structure design, which increases the friction between the wire rope and the pressure block, thereby further improving the clamping effect and ensuring that the wire rope is not easy to slip even under extreme conditions.

[0047] In summary, the utility model effectively improves the fixing and protection effect of the steel wire rope of the construction elevator in the shaft, avoids the occurrence of safety accidents, reduces maintenance costs, and provides a strong guarantee for safe use.

[0051] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0052] like Figure 1-3 As shown, a wire rope fixing and protecting device for a hoist in a hoistway, comprising:

[0053] Rack 1;

[0054] The torsion spring torsion force transmission mechanism comprises:

[0055] A mounting frame 21, the mounting frame 21 is fixed on the frame 1;

[0056] A first connecting shaft 22, the first connecting shaft 22 is rotatably mounted on one side of the mounting frame 21;

[0057] A torsion spring 23, wherein the torsion spring 23 is mounted on the mounting frame 21, and one end of the torsion spring 23 is connected to one end of the first connecting shaft 22;

[0058] A second connecting shaft 24, which is rotatably mounted on the other side of the mounting frame 21, and is connected to the other end of the torsion spring 23;

[0059] A connecting rod 3, the middle portion of which is fixed to the other end of the first connecting shaft 22;

[0060] An S-shaped guide wheel group, the S-shaped guide wheel group includes a first guide wheel 41 and a second guide wheel 42, the first guide wheel 41 and the second guide wheel 42 are hinged at both ends of the connecting rod 3, and the first guide wheel 41 and the second guide wheel 42 are suitable for forming an S-shaped wire rope channel;

[0061] When the steel wire rope is in a taut state, it is suitable for passing through the S-shaped steel wire rope channel and driving the first guide wheel 41 and the second guide wheel 42 to twist;

[0062] Wire rope clamping mechanism, the wire rope clamping mechanism comprises:

[0063] A mounting plate 51, the mounting plate 51 is fixedly connected to the mounting frame 21, and a threaded hole is provided on the mounting plate 51;

[0064] The mounting plate 51 is also provided with a wire rope guide groove;

[0065] A transmission rod 52, the transmission rod 52 is threadedly connected in the threaded hole, and the transmission rod 52 is connected to one end of the second connecting shaft 24;

[0066] A pressing block 53, which is mounted on the transmission rod 52 and is suitable for cooperating with the wire rope guide groove to form an extrusion channel;

[0067] When the steel wire rope is in a relaxed state, the torsion spring 23 is suitable for driving the pressing block 53 through the transmission rod 52 to clamp and fix the steel wire rope in the extrusion channel.

[0068] In this embodiment, if Figure 1-2 As shown, the steel wire rope first passes through the S-shaped steel wire rope channel formed by the S-shaped guide wheel group, and then passes through the steel wire rope guide groove on the mounting plate 51. In the process of passing through the S-shaped guide wheel group, namely the first guide wheel 41 and the second guide wheel 42, the tension of the steel wire rope itself not only drives the first guide wheel 41 and the second guide wheel 42 to twist, but also drives the twisting action of the torsion spring 23 through the first connecting shaft 22. As the torsion spring 22 twists, the transmission rod 52 on the second connecting shaft 24 on the opposite side of the torsion spring 22 rotates, and the pressure block 53 is loosened accordingly, so that the steel wire rope can smoothly pass through the steel wire rope guide groove when the steel wire rope works normally.

[0069] In the case of wire rope breakage, the S-shaped guide wheel group connected to the first connecting shaft 22 loses the torsion force brought by the wire rope, and the torsion spring 23 that loses the torsion force is transmitted to the second connecting shaft 24 on the other side and the transmission rod 52 connected to the second connecting shaft 24, and the transmission rod 52 rotates, thereby driving the pressing block 53 to tightly press the wire rope in the wire rope guide groove. This instant response mechanism greatly enhances safety protection and ensures that in the case of accidental wire rope breakage, measures can be taken quickly to avoid further safety accidents.

[0070] During use, there are generally two wire rope fixing and protection devices for the construction elevator in the shaft, which are respectively installed on the mobile elevator and the fixed elevator shaft. No matter which side of the wire rope is disconnected, the two wire rope fixing and protection devices for the construction elevator in the shaft will be activated to maximize safety by fixing the remaining side of the wire rope.

[0071] Specifically, Figure 1 As shown, the surface of the pressing block 53 that contacts the steel wire rope is the steel wire rope contact surface, and a sawtooth structure is provided on the steel wire rope contact surface;

[0072] On the wire rope guide groove of the mounting plate 51, a contact surface corresponding to the wire rope contact surface is provided with matching teeth meshing with the sawtooth structure.

[0073] In this embodiment, if Figure 1 As shown, the sawtooth structure on the pressing block 53 and the matching teeth on the guide groove of the mounting plate 51 can increase the contact area and friction force with the steel wire rope, thereby improving the clamping and fixing ability of the steel wire rope and preventing the steel wire rope from slipping.

[0074] In some embodiments, in addition to the sawtooth shape, the pressing block 53 and the guide groove may also be designed with other structures that increase friction, such as staggered transverse or longitudinal convex stripes, grid-like protrusions, etc.

[0075] Specifically, Figure 1-2 As shown, the wire rope fixing and protecting device for the hoist in the hoistway also includes a rotation angle adjustment mechanism, and the rotation angle adjustment mechanism includes:

[0076] A base shell, the base shell is mounted on the first connecting shaft 22;

[0077] A ratchet disc, which is mounted on the first connecting shaft 22 and is located inside the base shell. The outer periphery of the ratchet disc is provided with a plurality of ratchet teeth evenly distributed along the circumference;

[0078] A pawl is hinged in the base shell and is provided with a wedge-shaped end suitable for engaging with the ratchet teeth;

[0079] A spring, one end of the spring is connected to the pawl, and the other end of the spring is connected to the inner wall of the base shell, and the spring is suitable for keeping the pawl in a meshing state with the ratchet disc;

[0080] A handle 65, one end of which is fixedly connected to the ratchet disc.

[0081] In this embodiment, if Figure 1-2 As shown, the rotation angle adjustment mechanism can adjust the rotation angle of the first connecting shaft 22, thereby changing the preload force of the torsion spring 23 and the clamping force of the wire rope. The ratchet disc is rotated by the handle 65, and the ratchet disc drives the first connecting shaft 22 to rotate, and one end of the torsion spring 23 is twisted by force, and the pressure block at the other end is adjusted, thereby adjusting the tightness of the wire rope clamping.

[0082] Specifically, Figure 1 As shown, the wire rope fixing and protection device for the hoist in the hoistway also includes a locking mechanism, which includes:

[0083] The mounting frame 21 is provided with a locking hole 210;

[0084] A locking pin, which is slidably disposed in a locking hole 210 of the mounting frame 21;

[0085] A positioning hole is provided on the first connecting shaft 22, and the center of the positioning hole is adapted to coincide with the center of the locking hole 210;

[0086] The locking pin is adapted to pass through the locking hole 210 and the positioning hole to limit the rotation of the first connecting shaft 22 .

[0087] In this embodiment, if Figure 1-2 As shown, the locking mechanism is used to lock the first connecting shaft 22 at a set angle to prevent accidents during equipment transportation.

[0088] When the rotation angle adjustment mechanism rotates the first connecting shaft 22 to the set angle, the locking pin is inserted through the locking hole 210 on the mounting frame 21 and extends into the positioning hole of the first connecting shaft 22. Since the positioning hole is coaxial with the locking hole 210, the locking pin locks the first connecting shaft 22 to prevent it from further rotating. If readjustment is required, the locking pin can be pulled out of the positioning hole.

[0089] The diameter of the locking hole 210 and the positioning hole should match the diameter of the locking pin, and a certain matching clearance should be reserved to facilitate the insertion and removal of the locking pin. A lubricant is also applied to the surface of the locking pin to improve the smoothness of insertion and removal. To prevent the locking pin from falling off, a shoulder can be designed on the locking pin, and the shoulder rests on the outer surface of the mounting frame 21. A handle can be designed on the locking pin to facilitate manual gripping. A plurality of positioning holes evenly distributed along the circumference can be designed on the first connecting shaft 22 to increase the number of angle adjustment steps.

[0090] Specifically, Figure 1 and Figure 3 As shown, the wire rope fixing and protecting device for the construction elevator in the hoistway also includes a reversing wheel group 10, which is hinged on the frame 1, and the reversing wheel group 10 is suitable for guiding the wire rope to change direction between the S-shaped wire rope channel and the extrusion channel.

[0091] In this embodiment, if Figure 1-2 As shown, in actual use, the elevator wire rope reciprocates between the S-shaped guide wheel group and the extrusion channel of the clamping mechanism. In order to make the wire rope transition smoothly and reduce bending deformation, it is necessary to set a reversing wheel group 10 between the two components. The reversing wheel group 10 can guide the wire rope to change the direction of movement and reduce the bending degree of the wire rope.

[0092] The reversing wheel set 10 comprises a large wheel and a small wheel, and a 180-degree reversal is completed by the large wheel and the small wheel.

[0093] Specifically, Figure 1 As shown, the mounting frame 21 includes an upper cross frame 211 and a lower cross frame 212, and the upper cross frame 211 and the lower cross frame 212 are arranged in parallel and fixedly connected by a connecting plate;

[0094] The torsion spring 23 is loosely sleeved outside the upper cross frame 211 and the lower cross frame 212 .

[0095] In this embodiment, if Figure 1 As shown, by arranging the upper cross frame 211 and the lower cross frame 212 in parallel, a space for placing the torsion spring 23 can be formed outside the two.

[0096] The torsion spring 23 is sleeved on the outside of the upper cross frame 211 and the lower cross frame 212 in a clearance fit manner, with one end connected to the first connecting shaft 22 and the other end connected to the second connecting shaft 24. This arrangement facilitates the loading, unloading and replacement of the torsion spring 23. At the same time, since the outer diameter of the torsion spring is smaller than the cross frame spacing, the torsion spring 23 can rotate freely in the cross frame without causing interference friction with the cross frame. Between a part of the spirals of the torsion spring 23, there is also a limit bolt fixed on the upper cross frame 211 and the lower cross frame 212 to limit the axial movement of the torsion spring 23.

[0097] Specifically, Figure 1 As shown, the two ends of the torsion spring 23 are respectively provided with a first fixing hole and a second fixing hole;

[0098] A first U-shaped connecting member 25 is fixed on the first connecting shaft 22, and a first connecting hole corresponding to the first fixing hole is provided on the first U-shaped connecting member 25;

[0099] A second U-shaped connecting member 26 is fixed on the second connecting shaft 24, and a second connecting hole corresponding to the second fixing hole is provided on the second U-shaped connecting member 26;

[0100] A first fastener, which is adapted to pass through the first fixing hole and the first connecting hole to detachably connect one end of the torsion spring 23 to the first U-shaped connecting member 25;

[0101] The second fastener is adapted to be inserted into the second fixing hole and the second connecting hole to detachably connect the other end of the torsion spring 23 to the second U-shaped connecting member 26 .

[0102] In this embodiment, if Figure 1-2 As shown, a first U-shaped connector 25 and a second U-shaped connector 26 are provided between the torsion spring 23 and the first connecting shaft 22 and the second connecting shaft 24, so as to conveniently realize a detachable connection between the torsion spring 23 and the first connecting shaft 22 and the second connecting shaft 24. Compared with directly welding the torsion spring 23 to the first connecting shaft 22 and the second connecting shaft 24, the first U-shaped connector 25 and the second U-shaped connector 26 are more convenient for loading and unloading and replacing the torsion spring, thereby improving maintainability.

[0103] Specifically, Figure 1-2 As shown, the wire rope fixing and protection device for the construction elevator in the hoistway also includes a protective cover 7, and the protective cover 7 is installed outside the mounting frame 21.

[0104] In this embodiment, if Figure 1-2 As shown, the protective cover 7 mainly protects the wire rope fixing protection device to prevent dust, water vapor, oil and other external pollutants from entering the device and affecting its normal operation. At the same time, the protective cover also plays a safety protection role in preventing people from accidentally touching the moving parts in the device.

[0105] The protective cover 7 is fixed to the outside of the mounting frame 21 by bolt connection. Sufficient space should be reserved between the protective cover and the mounting frame to avoid interference with internal components. In addition, the protective cover is a split structure, which is easy to disassemble and transport.

[0106] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
