Description

Technical Field

[0001] The utility model relates to the technical field of small prefabricated parts manufacturing, in particular to a cable trough cover steel bar positioning tool. Background Art

[0002] Cable troughs are grooves for placing cables, usually used in building construction and formed by pouring concrete. Existing cable troughs are usually prefabricated and poured using molds. Since they are grooves, the thickness of the concrete pouring is destined not to be too thick, and in order to avoid the breakage of the groove, an appropriate amount of steel bars must be added inside it. In the traditional concrete structure pouring process, in order to avoid the phenomenon of exposed steel bars, stones are used to pad the steel bars, but due to the small thickness of the cable trough, stones cannot be used for padding. Not only that, the cable trough also needs to vibrate the concrete after pouring. During the vibration process, it is easy to vibrate the steel skeleton off the stone, which will cause the steel bars to be exposed, making the poured column protective layer unable to meet the design requirements.

[0003] In order to address the above problems, a cable trough cover steel bar positioning tool is urgently needed. Utility Model Content

[0004] The utility model aims to provide a cable trough cover steel bar positioning tool to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, a cable trough cover steel bar positioning tool is provided, comprising a side enclosure fixing frame, the side enclosure fixing frame is made of angle steel and is installed on a mold, and the side enclosure fixing frame is combined into a frame structure;

[0006] A lifting assembly, the lifting assembly is arranged on the side enclosure fixing frame, the lifting assembly comprises a hand-carrying rod, a vertical rod and a blocking rod, the hand-carrying rod and the vertical rod are combined to form an inverted "U"-shaped structure, the blocking rod is perpendicular to the vertical rod and parallel to the hand-carrying rod; the lifting assembly can also be used as a force application point during dismantling to facilitate dismantling of the device;

[0007] The positioning mechanism rotates and lifts the steel bars inside the template. The blocking rod also fixes the positioning mechanism, and the vertical rod also limits the rotation of the positioning mechanism.

[0008] Further, the positioning mechanism includes a limit tube, a lifting rod, and a suspension rod. The limit tube is fixedly connected to the side wall fixing frame. The lifting rod has an "L" - shaped structure. A spiral chute is arranged on the surface of the lifting rod. A slider connected to the chute is fixedly arranged on the inner wall of the limit tube. The lifting rod is inserted into the limit tube. The suspension rod is fixedly installed at the bottom end of the lifting rod. When the lifting rod rotates inside the limit tube, under the action of the chute and the slider, the lifting rod realizes the effect of lifting inside the limit tube, and the suspension rod connected to the lifting rod also realizes the lifting function accordingly.

[0009] Further, the lifting rod can rotate inside the limit tube, and as the lifting rod rotates, the lifting rod simultaneously realizes vertical displacement. When the lifting rod rises to the highest point, the top end of the lifting rod contacts both the vertical rod and the stop rod at the same time. At this time, the stop rod plays a supporting role for the lifting rod.

[0010] Further, the lifting assembly includes at least two groups and is symmetrically arranged. The positioning mechanism includes at least four. Every two of the positioning mechanisms form a group. Each group of the positioning mechanisms can be cooperatively connected with the lifting assembly on the same side. By setting four positioning mechanisms, the stability of the steel bars in the mold can be ensured.

[0011] Further, the suspension rod is perpendicularly connected to the bottom end of the lifting rod. The number of suspension rods is not less than two and is linearly arranged from top to bottom along the lifting rod. Placing the steel bars inside the mold on the suspension rods at different heights can adjust the position of the steel bars inside the mold.

[0012] Further, the outer wall of the limit tube has a regular hexagon structure, and the inner wall of the limit tube has a circular structure.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Rotate the lifting rod. Under the action of the chute and the slider, the lifting rod rises simultaneously. During the process of the lifting rod rotating and rising, the suspension rod lifts the steel bar framework inside the mold and suspends the steel bar framework to the central position of the mold as the lifting rod rises, ensuring that there will be no exposed - bar phenomenon after the steel bar framework is poured, and enabling the pouring protective layer to meet the design requirements.

[0015] In addition to being a structure convenient for disassembly and carrying, the lifting assembly can also fix and limit the rotation of the lifting rod through the stop rod and the vertical rod. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Those skilled in the art of the present technology can understand that unless specifically stated otherwise, the singular forms "a", "an" and "the" used herein may also include the plural forms. It should be further understood that the term "comprising" used in the specification of the present utility model means the presence of the described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0024] Please refer to Figures 1-3 As shown, a steel bar positioning tooling for a cable trench cover plate is provided, including a side wall fixing frame 1. The side wall fixing frame 1 is made of angle steel and is used for installation on the mold. The side wall fixing frame 1 is combined into a frame structure;

[0025] A lifting assembly 2 is provided on the side wall fixing frame 1. The lifting assembly 2 includes a hand-held rod 201, a vertical rod 202 and a stop rod 203. The hand-held rod 201 and the vertical rod 202 are combined into an inverted "U" - shaped structure. The stop rod 203 is perpendicular to the vertical rod 202 and parallel to the hand-held rod 201. The lifting assembly 2 can also be used as a force application point during removal to facilitate the removal of this device;

[0026] The positioning mechanism 3, the positioning mechanism 3 lifts the internal steel bars of the template by rotating, the stop bar 203 also plays a role in fixing the positioning mechanism 3, the vertical rod 202 also plays a role in restricting the rotation of the positioning mechanism 3, and the lifting assembly 2 and the positioning mechanism 3 are combined to realize the fixation of the steel bars in the mold.

[0027] As Figure 1 and Figure 2 shown, the positioning mechanism 3 includes a limit tube 301, a lifting rod 302, and a suspension rod 303. The limit tube 301 is fixedly connected to the side wall fixing frame 1. The lifting rod 302 has an "L" - shaped structure. A spiral chute 304 is arranged on the surface of the lifting rod 302. A slider 305 connected to the chute 304 is fixedly arranged on the inner wall of the limit tube 301. The lifting rod 302 is inserted into the limit tube 301. The suspension rod 303 is fixedly installed at the bottom end of the lifting rod 302. When the lifting rod 302 rotates inside the limit tube 301, under the action of the chute 304 and the slider 305, the lifting rod 302 realizes the effect of lifting inside the limit tube 301, and the suspension rod 303 connected to the lifting rod 302 also realizes the lifting effect accordingly;

[0028] At the same time, when the lifting rod 302 rotates and rises, the top end of the lifting rod 302 moves above the stop bar 203. At the same time, the vertical rod 202 also blocks the lifting rod 302, making it unable to rotate further.

[0029] Please refer to Figure 2 、 Figure 3 and Figure 4 shown:

[0030] The lifting rod 302 can rotate inside the limit tube 301. The rotatable angle of the lifting rod 302 is 0 - 90 degrees. And as the lifting rod 302 rotates, the lifting rod 302 synchronously realizes the up - and - down displacement. When the lifting rod 302 rises to the highest point, the top end of the lifting rod 302 contacts the vertical rod 202 and the stop bar 203 simultaneously. At this time, the stop bar 203 plays a supporting role for the lifting rod 302 to prevent the weight of the steel bars from driving the lifting rod 302 to descend;

[0031] As Figure 1 shown:

[0032] The lifting assembly 2 includes at least two groups and is symmetrically arranged. The positioning mechanism 3 includes at least four. Every two of the positioning mechanisms 3 form a group. Each group of the positioning mechanisms 3 can be cooperatively connected with the lifting assembly 2 on the same side. By setting four positioning mechanisms 3, the stability of the steel bars in the mold can be ensured.

[0033] The suspension rod 303 is vertically connected to the bottom end of the lifting rod 302. The number of the suspension rods 303 is not less than two, and they are linearly arranged in sequence from top to bottom along the lifting rod 302. The steel bars inside the mold are placed on the suspension rods 303 at different heights, so that the positions of the steel bars inside the mold can be adjusted to adapt to the prefabrication of cable ducts with different specifications.

[0034] The outer wall of the limiting tube 301 has a regular hexagonal structure, and the inner wall of the limiting tube 301 has a circular structure.

[0035] Working principle:

[0036] During use, rotate the lifting rod 302. During the rotation of the lifting rod 302, due to being blocked by the slider 305, and since the chute 304 is arranged around the outer wall of the lifting rod 302 and has a spiral structure, the lifting rod 302 can only rotate by moving up and down. Similarly, when the lifting rod 302 rotates, it will also move up and down synchronously. In this embodiment, rotate the lifting rod 302 by 90 degrees to make the lifting rod 302 rise to the highest point position. At this time, the lifting rod 302 will contact the vertical rod 202 and the stop rod 203 simultaneously, as shown in Figure 4 the state shown;

[0037] Before the lifting rod 302 rotates, the positional state relationship between the steel bars in the mold and the positioning mechanism 3 is as shown in Figure 3 shown;

[0038] Adjust all the positioning mechanisms 3 according to the same process. During this adjustment process, the suspension rod 303 will change from the state parallel to the steel bar at the beginning to the state of intersecting and contacting the steel bar. During this process, as the lifting rod 302 rises, the position of the steel bar will also rise, making it in the middle position of the mold, so that there is no need to worry about the phenomenon of exposed steel bars after pouring, as shown in Figure 4 shown;

[0039] After the concrete is poured and has initially set, rotate the lifting rod 302 in the reverse direction. At this time, as the lifting rod 302 rotates, the lifting rod 302 will move downward. During this process, the suspension rod will again become parallel to the steel bar. Subsequently, by pulling up the lifting assembly 2, the entire device can be taken out of the initially set concrete.

[0040] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
