Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to an auxiliary positioning device. Background Art

[0002] Prestressed floor technology is a high-performance building structure technology that uses prestressed anchor cables combined with reinforced concrete structure. It has significant advantages such as low structural weight, large usable clearance, and high structural crack resistance. It also has good thermal insulation and sound insulation performance characteristics. It is a cutting-edge technology among the ten new technologies. It is increasingly widely used in the floor parts of domestic public buildings, and its span and cross-section have repeatedly broken existing records. In large-span floor structures, the bottom plate and rib beam steel bars are installed, and the prestressed anchor cables are installed. After the anchoring process is completed, the anchor cables need to be fixed at the specified position in the middle of the rib beam according to the height and curvature shown in the design drawing. The positioning spacing is generally not more than 2m. Each rib beam is arranged with multiple anchor cables to form an anchor cable group. Each positioning point requires at least two operators to lift the anchor cable group first, temporarily fix it, and adjust the positioning position to be less than the limit before permanently fixing it.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, reference Figure 1-5 , is the first embodiment of the present utility model, which provides an auxiliary positioning device, including,

[0031] The support mechanism 100 includes a vertical rod 101;

[0032] The vertical pole 101 is set vertically to support the entire device. When in use, the vertical pole 101 is close to the rib beam reinforcement cage.

[0033] The lifting mechanism 200 includes a retractable assembly 201 arranged on the vertical pole 101, a traction rope 202 is wound on the retractable assembly 201, and a claw hook assembly 203 is provided at the other end of the traction rope 202. The claw hook assembly 203 includes two clamping jaws 203a hinged together with each other, and the upper ends of the two clamping jaws 203a are hinged with short rods 203b, and the upper ends of the two short rods 203b are hinged to each other. A connecting rope 203c is provided between the hinge of the two clamping jaws 203a and the hinge of the two short rods 203b, and a first spring 203d is provided on the connecting rope 203c.

[0034] The lifting mechanism 200 is used to lift the anchor cable to the positioning height, which is convenient for the operator to position and fix the anchor cable. Specifically, the vertical pole 101 is close to the rib beam reinforcement cage, and the lower part is placed on the bottom template, vertically supported on one side of the reinforcement cage, the claw hook assembly 203 is lowered, the claw hook assembly 203 is opened, the anchor cable is placed into the claw hook assembly 203, and the retracting assembly 201 is operated to lift the claw hook assembly 203 and the anchor cable to a suitable height. The anchor cable is manually held to the positioning position, and the anchor cable is tied to the rib beam reinforcement with an iron wire to complete the positioning and fixing of the anchor cable at the positioning point. Then the claw hook assembly 203 is lowered, and the above operation is repeated to realize the point-by-point positioning and installation of the anchor cable in the rib beam. The lower end of the clamping jaw 203a specifically extends inward to form a clamping portion to facilitate the lifting of the anchor cable. The two clamping jaws 203a are hinged by a short axis. Similarly, the upper ends of the two short rods 203b are also hinged by a short axis. The upper and lower ends of the connecting rope 203c are respectively fixed on the two short axis. The first spring 203d is in the middle of the connecting rope 203c, dividing the connecting rope 203c into two parts, upper and lower. When the traction rope 202 is lifted, the first spring 203d is pulled, and the first spring 203d is in a stretched state. When the traction rope 202 does not provide tension, the first spring 203d contracts, pulling the two short axis closer to each other, so that the two clamping jaws 203a are opened.

[0035] Furthermore, the support mechanism 100 also includes a cross bar 102 arranged at the top of the vertical pole 101, and a first pulley 103 and a second pulley 104 are respectively provided at both ends of the cross bar 102, and the traction rope 202 passes through the first pulley 103 and the second pulley 104 in sequence.

[0036] The setting of the cross bar 102 ensures that there is a certain distance between the lifting end of the traction rope 202 and the vertical pole 101 in the horizontal direction, avoiding the problem of the vertical pole 101 affecting the lifting due to the distance from the vertical pole 101 being too close during lifting. The setting of the first pulley 103 and the second pulley 104 makes the traction rope 202 move more smoothly and reduces wear.

[0037] Furthermore, the support mechanism 100 further includes an elastic rope 105 provided at the top of the vertical pole 101 , and there are at least two elastic ropes 105 .

[0038] The elastic rope 105 is provided to assist in stabilizing the vertical pole 101. Specifically, after the vertical pole 101 is close to the rib steel cage, the elastic rope 105 is pulled down and the lower end of the elastic rope 105 is fixed on the rib steel cage, so that the elastic rope 105, the rib steel cage and the vertical pole 101 form a triangular structure, thereby improving the overall stability of the vertical pole 101. In order to facilitate the fixation of the elastic rope 105, a hook is provided at the lower end of the elastic rope 105.

[0039] Furthermore, the support mechanism 100 further includes a base 106 disposed at the lower end of the upright 101 , and a non-slip pad 107 is disposed on the lower end surface of the base 106 .

[0040] The provision of the base 106 and the anti-slip pad 107 further enhances the stability of the placement of the upright pole 101 ; when in use, the base 106 is placed on the bottom template.

[0041] Example 2, reference Figure 1-8 , which is the second embodiment of the present utility model. Different from the previous embodiment, the retractable assembly 201 includes a mounting plate 201a arranged on the vertical pole 101, and a winch drum 201b is rotatably arranged on the mounting plate 201a. The end of the traction rope 202 away from the claw hook assembly 203 is wound around the winch drum 201b, and a first gear 201c is engaged with the winch drum 201b. The first gear 201c is engaged with the second gear 201d, and the second gear 201d is provided with a crank 201e.

[0042] The retracting and releasing assembly 201 is used to retract and release the traction rope 202, thereby realizing the lifting and lowering of the claw hook assembly 203; specifically, the hand crank 201e drives the second gear 201d to rotate, the second gear 201d drives the first gear 201c to rotate, and the first gear 201c drives the winch drum 201b to rotate, so that the traction rope 202 is wound on the winch drum 201b or unwound from the winch drum 201b.

[0043] Furthermore, the lifting mechanism 200 also includes a locking assembly 204, which includes a locking plate 204a rotatably set on the mounting plate 201a, one end of the locking plate 204a rests on the first gear 201c, and the other end of the locking plate 204a is provided with a second spring 204b, and the end of the second spring 204b away from the locking plate 204a is fixed on the mounting plate 201a, and a push rod 204c is provided at the upper position of the end of the locking plate 204a away from the first gear 201c, and a third spring 204d is sleeved on the push rod 204c.

[0044] The locking assembly 204 is used to limit the rotation of the winch drum 201b, which is convenient for operation. Specifically, when there is no need to retract the traction rope 202, one end of the locking plate 204a abuts against the first gear 201c, limiting the rotation of the first gear 201c, and thereby limiting the rotation of the winch drum 201b. When the traction rope 202 needs to be retracted or released, the top rod 204c is pressed down, and the top rod 204c squeezes the locking plate 204a away from one end of the first gear 201c, so that the end of the locking plate 204a abuts against the first gear 201c and disengages from the first gear 201c, thereby releasing the restriction on the rotation of the first gear 201c.

[0045] Furthermore, the retractable assembly 201 also includes a shell 201f covering the outside of the winch drum 201b, the shell 201f is fixed on the mounting plate 201a, the top rod 204c is vertically passed through the shell 201f, the upper end of the third spring 204d is fixed on the inner wall of the top end of the shell 201f, and the lower end of the third spring 204d is fixed on the top rod 204c.

[0046] The outer shell 201f is used to protect the winch drum 201b and the traction rope 202. When the top rod 204c is pressed, the third spring 204d is in a stretched state. When the top rod 204c is released, the third spring 204d contracts, driving the top rod 204c to move upward, releasing the squeezing of the locking plate 204a. The second spring 204b tightens the locking plate 204a due to the elastic force, causing the locking plate 204a to contact the first gear 201c, thereby achieving automatic locking.

[0047] Example 3, reference Figure 1-8 , which is the third embodiment of the present utility model. Different from the previous embodiment, a slide groove 108 is provided on the cross bar 102. The slide groove 108 is arranged along the length direction of the cross bar 102. A slide rod 109 is provided in the slide groove 108. The second pulley 104 is rotatably provided on the slide rod 109.

[0048] The setting of the slide groove 108 is used to adjust the horizontal position of the hoisting. Specifically, the slide rod 109 slides in the slide groove 108 so that the second pulley 104 and the vertical pole 101 have a certain distance in the horizontal direction. The traction rope 202 passes through the second pulley 104 and then connects to the claw hook assembly 203. The lower position of the second pulley 104 is the hoisting position.

[0049] Furthermore, a positioning bolt 110 is provided between the slide bar 109 and the cross bar 102 .

[0050] The positioning bolt 110 is used to lock the relative positions of the slide bar 109 and the cross bar 102 , thereby locking the position of the second pulley 104 .

[0051] Furthermore, the anti-slip pad 107 is a rubber pad.

[0052] Through the setting of the support mechanism 100 and the lifting mechanism 200, the anchor cable on the bottom plate can be quickly picked up and easily lifted to the specified position. After precise positioning, it is fixed once and for all with iron wire, and then quickly moved to the next positioning point. The device only requires one operator to complete the step-by-step operation, which saves one laborer compared to the traditional method. Under the method of assisting the lifting, positioning and fixing of the anchor cable by the device, on-site actual measurement shows that the speed is more than 3 times faster than the conventional method, which reduces labor intensity and greatly improves work efficiency.
