Description

Technical Field

[0001] This invention relates to the field of excavation auxiliary structure technology, and in particular to an integrated construction device for line excavation. Background Technology

[0002] When constructing underground power transmission lines, underground excavation is required. This usually requires manual labor using tools such as shovels and picks to excavate and clear the soil. This is labor-intensive and can easily lead to deviations in foundation dimensions, affecting the quality of construction.

[0003] Secondly, in existing technologies, when excavating underground manually, the excavated soil and rocks need to be hoisted to the ground for dumping and transfer. During the hoisting process, a certain distance must be maintained between the hopper and the well wall. When reaching the wellhead, the hopper needs to be manually pulled to assist in completing the dumping step. This requires real-time human supervision and assistance, and there is room for improvement. Therefore, an integrated construction device for line excavation is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing an integrated construction device for line excavation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an integrated construction device for line excavation, comprising: Install the support frame on the ground and directly above the wellhead; The soil lifting mechanism is located on top of the support frame, and its output end is equipped with a hoisting rope, which is connected to the soil lifting bucket. A deflection mechanism is movably mounted on a support frame and installed in a staggered manner with the soil lifting mechanism. A connecting slot is provided on the deflection mechanism, and a lifting crossbar is provided at the top of the soil lifting hopper. The lifting crossbar is used to engage with the connecting slot when the soil lifting hopper is lifted to the top. The deflection mechanism is used to deflect the soil hopper to one side under the drive of the soil lifting mechanism when the hopper is lifted to the top, so as to offset it from the wellhead for easy material discharge.

[0006] Furthermore, an installation platform is provided on the top of the mounting bracket; The soil lifting mechanism includes a first lifting motor, which is mounted on an installation platform. The output end of the first lifting motor is equipped with a winding roller, and the installation platform has a rope release opening.

[0007] Furthermore, the deflection mechanism includes two sets of connecting frames arranged opposite each other; A bearing roller and multiple guide rollers are rotatably arranged between the two sets of connecting frames; The two sets of connecting frames, the bearing rollers, and the multiple guide rollers form a whole; It also includes a rotating seat located at the bottom of the installation platform and corresponding to the rope release port; The rotating seat is rotatably connected to the carrying roller, and the carrying roller is offset from the winding roller.

[0008] Furthermore, the soil lifting hopper includes a lifting crossbar, which is cylindrical, and both ends of the lifting crossbar are provided with adjusting brackets; Both sets of the adjustment brackets consist of two sets of adjustment rods. The top ends of the two sets of adjustment rods intersect and are located at the center of the end of the lifting crossbar. The included angle between the two sets of adjustment rods is adjustable. The lifting crossbar is provided with locking components at both ends for locking the angles of the two sets of adjusting support rods; Both sets of adjustment brackets are equipped with folding hoppers at their bottoms.

[0009] Furthermore, a crossbar is provided on the side of the mounting bracket near the deflected soil hopper; The abutting crossbar is used to contact the adjusting bracket during the deflection of the soil hopper, so that the folding hopper is in an inclined position.

[0010] Furthermore, a feeding mechanism is provided on the side of the mounting bracket near the contact crossbar; The feeding mechanism includes a screening hopper corresponding to the deflected soil lifting hopper and a transfer bin located below the screening hopper; The screening hopper is used to screen out gravel from the soil layer and temporarily store it therein; The transfer chamber is located below the screening hopper to receive the screened soil and facilitate its subsequent transfer.

[0011] Furthermore, a lifting motor is also provided on the top of the installation platform, and a safety rope is provided at the output end of the lifting motor; The installation platform has a safety opening corresponding to the safety rope.

[0012] Furthermore, a ladder is provided on the side of the mounting bracket away from the unloading mechanism; The ladder is a flexible ladder, and one end of the ladder is hung on a mounting bracket.

[0013] Furthermore, a ventilation mechanism is provided on the side of the mounting bracket, and an atomizing dust suppression mechanism is provided at the output end of the ventilation mechanism.

[0014] Furthermore, the top of the installation platform is also equipped with a lighting and measurement system to provide lighting below the wellhead and to detect the wellhead depth and the verticality of the excavation.

[0015] The beneficial effects of this invention are reflected in: This invention allows for the lifting of soil and rocks excavated by underground construction workers into a hopper. The hopper can then be lifted to the wellhead by a lifting mechanism. When the hopper reaches its maximum height, its lifting crossbar engages with a connecting slot on a deflection mechanism. The lifting mechanism continues to operate. Because the lifting and deflection mechanisms are installed in a staggered manner, the hopper can be deflected away from the center of the wellhead by using the end of the deflection mechanism as its center and its length as its radius. This facilitates dumping and avoids the need for ground construction workers to manually pull and assist the hopper's deflection after it has been hoisted to the top. This improves construction efficiency and avoids safety hazards. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-4 This invention discloses an integrated construction device for power line excavation, comprising: Mounting bracket 1 is placed on the ground and located directly above wellhead 01, as follows. Figure 1 As shown, the mounting bracket 1 is a conical structure composed of multiple metal tubes. It is easy to imagine that the bottom of the mounting bracket 1 should also be equipped with a fixing mechanism (not shown in the figure) that can be inserted into the soil layer around the wellhead 01 to improve the overall stability of the mounting bracket 1. Secondly, a protective net (not shown in the figure) is also installed around the bottom of the mounting bracket 1 to prevent objects from falling when construction workers are working in the well, thereby improving construction safety. The soil lifting mechanism 2 is located on the top of the support frame 1, and its output end is equipped with a hoisting rope, which is connected to the soil lifting bucket 4. It is easy to imagine that the soil lifting mechanism 2 is a forward and reverse motor, which can drive the soil lifting bucket 4 to lift and lower. The deflection mechanism 8 is movably mounted on the mounting bracket 1 and is installed in a staggered manner with the soil lifting mechanism 2. The deflection mechanism 8 is provided with a connecting slot 84. The top of the soil lifting hopper 4 is provided with a lifting crossbar 41. The lifting crossbar 41 is used to engage with the connecting slot 84 when the soil lifting hopper 4 is lifted to the top. The connecting slot 84 is an arc-shaped buckle and has a guide surface on its outward side. The deflection mechanism 8 is used to drive the soil lifting hopper 4 to deflect to one side under the drive of the soil lifting mechanism 2 when the soil lifting hopper 4 is lifted to the top, so as to offset it from the wellhead 01 for easy material discharge.

[0020] With the above-mentioned structural design, after the soil and rocks excavated by the underground construction workers are placed in the soil lifting hopper 4, the soil lifting mechanism 2 can drive the soil lifting hopper 4 to the wellhead. When the soil lifting hopper 4 is lifted to its maximum extent, its lifting crossbar 41 is engaged in the connecting slot 84 on the deflection mechanism 8. Then the soil lifting mechanism 2 continues to operate. Since the soil lifting mechanism 2 and the deflection mechanism 8 are installed in a staggered manner, the soil lifting hopper 4 can be deflected towards the side away from the center of the wellhead 01 with the end of the deflection mechanism 8 as the center and its length as the radius, so as to facilitate dumping. This avoids the problem that the ground construction workers need to manually pull the soil lifting hopper 4 to assist in deflection after it is hoisted to the top, which improves construction efficiency and avoids safety hazards.

[0021] In a preferred embodiment, the top of the mounting bracket 1 is provided with an installation platform, which is welded to the mounting bracket 1. Preferably, the installation platform is a metal platform. The soil lifting mechanism 2 includes a first lifting motor, which is mounted on an installation platform. The output end of the first lifting motor is provided with a winding roller 21, and the installation platform has a rope release opening.

[0022] In this application, the deflection mechanism 8 includes two sets of connecting frames arranged opposite each other. The two sets of connecting frames are arc-shaped pieces, and the center of the arc-shaped pieces and the center of the take-up roller 21 are on the same vertical line. A bearing roller 82 and a plurality of guide rollers 83 are rotatably arranged between the two sets of connecting frames. Preferably, there are five sets of guide rollers 83, and the five sets of guide rollers 83 are arranged in an arc shape. The hoisting rope is arranged in an arc shape along the outer surface of the first four sets of guide rollers 83 and passes through the last set of guide rollers 83 corresponding to the connecting bayonet 84. The two sets of connecting frames, the bearing roller 82, and the multiple guide rollers 83 form a whole; It also includes a rotating seat 81 located at the bottom of the installation platform and corresponding to the rope release port; The rotating seat 81 is rotatably connected to the carrying roller 82, and the carrying roller 82 is offset from the winding roller 21.

[0023] With the above structural setup, when the hoisting rope is under force, the deflection mechanism 8 is in a vertical state due to gravity. During the lifting process of the soil bucket 4, the deflection mechanism 8 will deflect slightly to one side due to friction. When it is lifted to the maximum limit, the lifting crossbar 41 set on it is engaged in the connecting slot 84. Then, under its limit, when the hoisting rope continues to be stretched, the deflection mechanism 8 will rotate significantly, realizing the offset of the soil bucket 4.

[0024] In this application, the soil lifting hopper 4 includes a lifting crossbar 41, which is cylindrical, and both ends of the lifting crossbar 41 are provided with adjusting brackets 42. Both sets of the adjusting brackets 42 are composed of two sets of adjusting rods. The top ends of the two sets of adjusting rods intersect and are located at the center of the end of the lifting crossbar 41. The included angle between the two sets of adjusting rods is adjustable. The lifting crossbar 41 is provided with locking components 43 at both ends for locking the angles of the two sets of adjusting support rods; The bottom of both sets of adjusting brackets 42 is provided with folding hoppers 44.

[0025] With the above-mentioned structural configuration, the folding hopper 44 can adjust its volume by adjusting the two sets of adjusting brackets 42, thereby adapting to different working environments. It can also be fixed by locking component 43 to lock its range.

[0026] It should be noted that the mounting bracket 1 is provided with an abutting crossbar on the side near the deflected soil hopper 4; The abutting crossbar is used to contact the adjusting bracket 42 during the deflection of the soil lifting hopper 4, so that the folding hopper 44 is in an inclined position.

[0027] In this application, the mounting bracket 1 is provided with a feeding mechanism 5 on the side near the crossbar; The feeding mechanism 5 includes a screening hopper 51 corresponding to the deflected soil lifting hopper 4 and a transfer bin 52 located below the screening hopper 51. The screening hopper 51 is used to screen out gravel in the soil layer and temporarily store it therein; The transfer chamber 52 is movably disposed below the screening hopper 51 to receive the screened soil and facilitate subsequent transfer.

[0028] The feeding mechanism 5 is used to receive the soil and rocks poured out by the soil lifting hopper 4. Then, the stones in the soil and rocks are screened through the screening hopper 51. It should be added that a vibration mechanism (not shown in the figure) is provided on the mounting bracket 1. The vibration mechanism is used to drive the screening hopper 51 to vibrate, which has the effect of vibration screening. The screening hopper 51 is detachably mounted on the mounting bracket 1 to facilitate the subsequent cleaning of the stones temporarily stored inside.

[0029] It is easy to imagine that a lifting motor 3 is also provided on the top of the installation platform, and a safety rope is provided at the output end of the lifting motor 3; The installation platform is provided with a safety opening corresponding to the safety rope. This application can use the lifting motor 3 as a safety protection measure to quickly assist construction personnel in getting out of the wellhead 01 in special circumstances.

[0030] It is easy to imagine that a ladder 7 is provided on the side of the mounting bracket 1 away from the unloading mechanism 5; The ladder 7 is a flexible ladder, and one end of the ladder 7 is hung on the mounting bracket 1, so that construction personnel can go down into the well to work.

[0031] In this application, a ventilation mechanism 6 is provided on the side of the mounting bracket 1, and an atomizing dust suppression mechanism is provided at the output end of the ventilation mechanism 6. The ventilation mechanism and the atomizing dust suppression mechanism are conventional technical means in the prior art, and therefore are not described in detail in this application.

[0032] In this application, it is readily apparent that a gas detection mechanism is installed at the bottom of the safety rope, flexible ladder, or ventilation mechanism 6. This mechanism can be set at a corresponding position according to actual implementation needs. Its purpose is to monitor whether there are abnormal fluctuations in the presence of harmful gases and oxygen content in the well. The gas detection mechanism is electrically connected to the ventilation mechanism 6 and should also be equipped with an abnormal alarm mechanism electrically connected to it. This alarm is used to remind personnel to evacuate, issue an alarm, and simultaneously activate the ventilation mechanism 6 when the harmful gas level exceeds the standard or the oxygen content is insufficient, so as to maintain a safe working environment in the well. It should be noted that the above-mentioned mechanism is a conventional technical means in the prior art, and therefore it is not described in detail in this application.

[0033] Finally, it should be noted that the top of the installation platform is also equipped with a lighting and measurement system to provide lighting below the wellhead 01 and to detect the depth of the wellhead 01 and the verticality of the excavation.

[0034] With the above-mentioned structural setup, the lighting system can provide supplemental lighting for underground construction operations, making it easier for construction personnel to work, while the measurement system provides reference for underground personnel to adjust the verticality of the construction and avoid construction deviations.

[0035] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0037] Additionally, "multiple" refers to two or more.

[0038] The above description is only a preferred embodiment of the present invention and is 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 within the protection scope of the present invention.
