Description

Technical Field

[0001] The invention relates to the technical field of steel bar binding construction, and in particular to an automatic fast steel bar threading device in a narrow space. Background Art

[0002] The existing method of arranging steel bars in a small space usually requires several workers to cooperate in threading the steel bars. The workers use a hook rod made of steel bars to reach into places that people cannot reach, and then several workers stand in the front, middle and back positions, and gradually thread the steel bars by hooking the steel bars together and dragging them. In addition, there are also some steel bar threading devices, which are mainly divided into two types. Taking the threading of the bottom reinforcement of a large-section beam as an example, one is to use several brackets to support and lift all the steel bars of the entire beam, and after all the longitudinal steel bars and stirrups are tied, the beam steel bars are placed in the template as a whole by adjusting the height. The other is to thread the steel bars from one end of the beam when there is available space at one end of the beam.

[0003] For example, a Chinese patent discloses a method for vertical lifting of steel bars in a narrow space based on an integral platform (publication number: CN106223625B), which includes: setting a first workstation on the integral platform to assemble steel bars to form a steel bar group; setting a second workstation above the steel bar working surface on the integral platform to lift the steel bar group from the first workstation to the second workstation to vertically lower the steel bar group; setting a third workstation on the lower hanging frame of the integral platform to guide the steel bar group to vertically lower; setting a fourth workstation on the steel bar working surface on the lower hanging frame of the integral platform to unbind the steel bar group lowered to the steel bar working surface and install the steel bars. By rationally planning the division of multi-person flow operation steps and the arrangement of personnel and mechanical workstations during the process of vertical lifting of steel bars, the steel bars can be quickly and safely transported from the top of the platform to the steel bar working surface in batches, eliminating the safety hazards of traditional methods such as using ordinary rope slings and manual one-by-one and step-by-step delivery, and improving the efficiency of steel bar transportation.

[0004] Currently, both of these two reinforcement threading tools have limitations. The first one is inefficient, and there are too many steel bars in large-section beams, which poses a great safety risk to its stability. The second one has high space requirements. In most cases, there is no space at the end of the beam to arrange the equipment. In addition, when the beam is long, the inserted steel bars are prone to bend down and insert into the formwork. The overall construction efficiency and feasibility are low. Therefore, the most common way of threading reinforcement is to manually use a hook to drag.

[0005] Therefore, it is necessary to propose an automated rapid reinforcing bar threading device in a narrow space to solve the above problems. Summary of the invention

[0047] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a lifting and advancing device for reinforcing bar threading, wherein, when reinforcing bar threading is being performed, the advancing device repeatedly moves in a small space to quickly and automatically thread the reinforcing bar, and threading one-half of the circumference of the reinforcing bar in each movement cycle, and the device for lifting the reinforcing bar returns to its position when one-half of the circumference is left, so that the automated machinery can quickly move back and forth within a small range instead of manual dragging; the present invention is simple to construct and has a reasonable structural force, and accelerates the reinforcing bar threading speed in a narrow space by converting the circular motion of the motor bearing into an efficient elliptical motion path; compared with traditional reinforcing bar threading, there is no increase in working surfaces and pre-working conditions, and there is no need to set up a special construction site; the present invention saves a lot of physical labor of traditional workers in reinforcing bar threading and solves unsafe hidden dangers, which not only improves construction efficiency and reduces the number of workers, but also ensures the personal safety of construction workers.

[0048] During use, the construction method of the present invention is carried out according to the following steps.

[0049] Step 1: Taking the reinforcement binding of large-section beams as an example, first place the beam surface reinforcement and stirrups, and install the stirrups and tie them together to fix the spacing, then place the beam area and stirrups into the beam mold.

[0050] Step 2: Place the reinforcement penetration device described in the present invention on the template at the beam end where the reinforcement is inserted, and configure the motor and motor power supply.

[0051] Step 3: Place a small section of the steel bar into the beam, about 1m in length, so that the three hooks of the device extending into the beam can touch each other.

[0052] Step 4: Adjust the two adjustable steel bar support rods on the left and right of the device, and lift the steel bar about 5 cm so that it does not contact the stirrups and the beam formwork.

[0053] Step 5: Start the motor or manually rotate the adjustable movable pull rod of the device to the middle, and turn the adjustment device to make the lower hook closely contact with the steel bar.

[0054] Step 6: Start the motor, the adjustable moving rod will push the steel bar forward through half of the elliptical cycle, and then place the steel bar on the support rods at both ends to complete the second half of the cycle, and then automatically pull the steel bar forward again, thus achieving fast and automatic penetration.

[0055] Step 7: For very long steel bars, the front end will bend and fall into contact with the template after being inserted too long, thereby increasing the friction setting and completely inserting the template, making it impossible to continue inserting. It is necessary to use an ordinary hook to slightly lift the end of the steel bar.

[0056] Step 8: After the current steel bar is inserted, the next steel bar can be quickly inserted by moving the adjusting device left and right on the slide rail.

[0057] The present invention is easy to construct, quick to install, and low in cost. By converting the rotation of the motor into elliptical motion and assisted by a stabilizing and supporting device, the adjustable pull rod can move repeatedly within a small range, thereby realizing automatic rapid reinforcing bar threading. The present invention overcomes the shortcomings of traditional reinforcing bar threading, such as low efficiency, potential safety hazards, and large requirements for the working surface. The device is easy to install, and no human intervention is required after the device is in operation, thereby ensuring safety.

[0058] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
