Technical Field
[0001] This utility model belongs to the field of oil pipe protection technology, specifically relating to a hydraulic oil pipe sorting and protection structure for an excavation trolley. Background Technology
[0002] During tunnel excavation, workers typically stand on a trolley to drill holes, which are about 3-5 meters deep and no more than 10 centimeters in diameter. Explosives are then filled into the holes for blasting. To ensure safety, the trolley needs to be moved to a position more than 80 meters away from the borehole during blasting. However, even at this distance, the gas flow generated by the explosion can still easily affect the hydraulic lines on the trolley, causing damage to the hydraulic lines, affecting the normal use of the excavation trolley, increasing equipment maintenance costs and the risk of construction delays.
[0003] To address this issue, a hydraulic oil pipe management and protection structure for the excavation trolley was designed. Utility Model Content
[0004] To address the problems mentioned in the background section, this invention provides a hydraulic pipe arrangement and protection structure for an excavation trolley. This structure utilizes its spherical shape to effectively disperse the impact force of the blasting airflow, significantly reducing the pulling force of the airflow on the hydraulic pipes and decreasing the probability of damage to the hydraulic lines due to the blasting airflow.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic oil pipe arrangement and protection structure for an excavation trolley, comprising a trolley body, a first working platform and a second working platform arranged on the side of the trolley body, a U-shaped frame fixedly connected to the surface of the trolley body, an upper hemispherical cover and a lower hemispherical seat arranged inside the U-shaped frame, the bottom surface of the upper hemispherical cover and the upper surface of the lower hemispherical seat forming a spherical shape when they are attached together, the upper hemispherical cover and the lower hemispherical seat forming a spherical shape are used to protect the hydraulic oil pipe.
[0006] As a preferred embodiment of the hydraulic oil pipe arrangement and protection structure of the excavation trolley of this utility model, the upper part of the upper hemispherical cover is fixedly connected to the upper disc via a connecting rod. The upper disc is fixedly connected to the inside of the U-shaped frame. The bottom end of the U-shaped frame is fixedly connected to the lower disc. A threaded rod is inserted into a threaded hole opened inside the lower disc. The threaded rod is threadedly connected to the lower disc through the threaded hole. The threaded rod is rotatably connected to the lower hemispherical seat via a bearing.
[0007] As a preferred embodiment of the hydraulic oil pipe arrangement and protection structure of the excavation trolley of this utility model, a sliding rod is inserted into a plurality of sliding holes opened on the surface of the lower disc, the lower disc and the sliding rod are slidably connected, and the top end of the sliding rod is fixedly connected to the lower hemispherical seat.
[0008] As a preferred embodiment of the hydraulic oil pipe arrangement and protection structure of the excavation trolley of this utility model, the upper surface of the lower hemispherical seat is fixedly connected with a ring strip, the upper surface of the ring strip is provided with an annular cross-section, and the bottom surface of the upper hemispherical cover is provided with an annular groove.
[0009] As a preferred embodiment of the hydraulic oil pipe arrangement and protection structure of the excavation trolley of this utility model, the surface of the upper hemispherical cover away from the second working platform is provided with multiple oil passage holes.
[0010] As a preferred embodiment of the hydraulic oil pipe arrangement and protection structure of the excavation trolley of this utility model, a support rod is fixedly connected to the surface of the diagonal brace between the second working platform and the trolley body. The support rod is used to hang the hydraulic oil pipe inside the space formed by the upper hemisphere cover and the lower hemisphere seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the spherical structure formed by the upper hemispherical cover and the lower hemispherical seat can effectively disperse the airflow impact force generated by the explosion by utilizing the characteristics of the spherical shape, greatly reducing the pulling force of the airflow on the hydraulic oil pipe, reducing the probability of damage to the hydraulic pipeline due to the impact of the explosion airflow. At the same time, the cooperation between the ring bar and the ring groove enhances the sealing performance of the spherical structure, preventing airflow from entering the interior through the gaps. The oil passage hole is set on the side opposite to the explosion area, further reducing the direct impact of the explosion airflow on the internal hydraulic oil pipe through the oil passage hole, and comprehensively improving the protection of the hydraulic oil pipe.
[0013] By rotating the threaded rod of the second working platform, the lower hemisphere can be moved away from the upper hemisphere cover, thus separating the upper hemisphere cover from the lower hemisphere. This allows workers to regularly inspect and maintain the internal hydraulic oil pipes, promptly detect and address potential leaks in the hydraulic lines, ensure the normal operation of the excavation trolley's hydraulic system, and reduce the risk of construction interruptions due to equipment failure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figures 1 to 7 As shown;
[0026] A hydraulic oil pipe arrangement and protection structure for an excavation trolley includes a trolley body 1, a first working platform 101 and a second working platform 102 arranged on the side of the trolley body 1, a U-shaped frame 2 fixedly connected to the surface of the trolley body 1, an upper hemispherical cover 3 and a lower hemispherical seat 4 arranged inside the U-shaped frame 2, the bottom surface of the upper hemispherical cover 3 and the upper surface of the lower hemispherical seat 4 are attached together to form a spherical shape, the upper hemispherical cover 3 and the lower hemispherical seat 4 forming a spherical shape are used to protect the hydraulic oil pipe.
[0027] It should be noted that the U-shaped frame 2 provides stable support for the upper hemispherical cover 3 and the lower hemispherical seat 4. The spherical structure can wrap the hydraulic oil pipes within it. Combined with the working positions of the first working platform 101 and the second working platform 102, it can effectively block the impact of the blasting airflow on the hydraulic oil pipes and reduce the damage to the oil pipes caused by the airflow.
[0028] Furthermore:
[0029] In an optional embodiment, the upper part of the upper hemispherical cover 3 is fixedly connected to the upper disk 6 via a connecting rod 7. The upper disk 6 is fixedly connected to the inside of the U-shaped frame 2. The bottom end of the U-shaped frame 2 is fixedly connected to the lower disk 5. A threaded rod 12 is inserted into the threaded hole 13 inside the lower disk 5. The threaded rod 12 is threadedly connected to the lower disk 5 via the threaded hole 13. The threaded rod 12 is rotatably connected to the lower hemispherical seat 4 via a bearing 11.
[0030] It should be noted that the connecting rod 7 and the upper disc 6 cooperate to make the upper hemispherical cover 3 stable in the U-shaped frame 2. The threaded connection between the threaded rod 12 and the lower disc 5 and the rotational cooperation of the bearing 11 can drive the lower hemispherical seat 4 to rise and fall by rotating the threaded rod 12, thereby realizing the opening and closing of the upper hemispherical cover 3 and the lower hemispherical seat 4.
[0031] Furthermore:
[0032] In an optional embodiment, a sliding rod 10 is inserted into a plurality of sliding holes 9 on the surface of the lower disk 5, the lower disk 5 and the sliding rod 10 are slidably connected, and the top end of the sliding rod 10 is fixedly connected to the lower hemispherical seat 4.
[0033] It should be noted that the sliding of the slide rod 10 within the sliding hole 9 provides precise guidance for the lifting and lowering of the lower hemisphere 4, preventing the lower hemisphere 4 from shifting during movement, ensuring a smooth opening and closing process between the upper hemisphere cover 3 and the lower hemisphere 4, and guaranteeing the stable operation of the structure during the operation of the first working platform 101 and the second working platform 102.
[0034] Furthermore:
[0035] In an optional embodiment, a ring 15 is fixedly connected to the upper surface of the lower hemisphere 4, the upper surface of the ring 15 is provided with an annular cross-section, and an annular groove 14 is provided on the bottom surface of the upper hemisphere 3.
[0036] It should be noted that the ring bar 15 is inserted into the ring groove 14, and the annular cross-section enhances the sealing and firmness of the connection between the two, preventing the burst airflow from entering the interior through the gap, ensuring effective protection for the hydraulic oil pipe located near the trolley body 1, and reducing the impact of airflow on the oil pipe.
[0037] Furthermore:
[0038] In an optional embodiment, the surface of the upper hemispherical cover 3 away from the second working platform 102 is provided with a plurality of oil passage holes 16.
[0039] It should be noted that: the oil passage 16 provides a channel for the hydraulic oil pipe to enter and exit the spherical space. Its setting away from the second working platform 102 and facing away from the blasting area can reduce the impact of the blasting gas flow through the oil passage 16 on the internal oil pipe, and at the same time facilitate the extension of the oil pipe from the trolley body 1 to the required position, avoiding pipe entanglement.
[0040] Furthermore:
[0041] In an optional embodiment, a support rod 17 is fixedly connected to the surface of the diagonal brace between the second working platform 102 and the trolley body 1. The support rod 17 is used to hang the hydraulic oil pipe inside the space formed by the upper hemispherical cover 3 and the lower hemispherical seat 4.
[0042] It should be noted that: support rod 17 provides orderly suspension points for hydraulic oil pipes, so that the oil pipes are neatly arranged in the spherical space, avoiding damage due to disorder under the action of airflow, and at the same time facilitating the staff to inspect and maintain the oil pipes on the second working platform 102.
[0043] Furthermore:
[0044] In an optional embodiment, a clearance groove 8 is provided on the surface of the upper hemisphere cover 3, and the diagonal brace between the second working platform 102 and the trolley body 1 is inserted inside the clearance groove 8, and the support rod 17 is located inside the upper hemisphere cover 3.
[0045] It should be noted that the clearance groove 8 provides space for the diagonal brace, ensuring that when the upper hemisphere cover 3 and the lower hemisphere seat 4 are closed, the support rod 17 provides orderly suspension for the hydraulic oil pipe inside the upper hemisphere cover 3 and the lower hemisphere seat 4.
[0046] Working principle: When it is necessary to protect the hydraulic oil pipe, the bottom surface of the upper hemisphere cover 3 fits against the upper surface of the lower hemisphere seat 4 to form a spherical structure. At this time, the ring strip 15 on the upper surface of the lower hemisphere seat 4 is inserted into the ring groove 14 on the bottom surface of the upper hemisphere cover 3, which enhances the sealing and firmness of the connection between the two and prevents the burst gas from entering the interior through the gap and affecting the hydraulic oil pipe.
[0047] The hydraulic oil pipe enters the spherical structure through multiple oil passage holes 16 opened on the surface of the upper hemispherical cover 3 away from the second working platform 102, and is hung on the support rod 17. Since the multiple oil passage holes 16 are all located on the side of the upper hemispherical cover 3 away from the blasting area, the possibility of the blasting gas directly impacting the internal hydraulic oil pipe through the oil passage holes 16 can be reduced during the blast. At the same time, the spherical structure can disperse the impact force of the gas flow generated by the blast by utilizing its shape characteristics, which can greatly reduce the pulling force of the gas flow on the hydraulic oil pipe, thereby effectively protecting the hydraulic oil pipe.
[0048] When the hydraulic oil pipe needs to be inspected periodically, rotate the threaded rod 12. Since the threaded rod 12 is threadedly connected to the lower disk 5 through the threaded hole 13 and rotatably connected to the lower hemisphere seat 4 through the bearing 11, the lower hemisphere seat 4 will move away from the upper hemisphere cover 3 under the action of threaded transmission. During this process, the lower hemisphere seat 4 drives the slide rod 10 to slide in the slide hole 9 of the lower disk 5. The slide rod 10 plays a guiding role to ensure that the lower hemisphere seat 4 moves smoothly, so that the upper hemisphere cover 3 is separated from the lower hemisphere seat 4, so that the staff can perform inspection operations on the internal hydraulic oil pipe.
[0049] In addition, the upper hemispherical cover 3 is fixed to the upper disc 6 by the connecting rod 7. The upper disc 6 and the lower disc 5 are both fixed inside the U-shaped frame 2, which is in turn fixed to the surface of the trolley body 1. Combined with the supporting effect of the slide rod 10, the stability of the upper hemispherical cover 3 and the lower hemispherical seat 4 is ensured when subjected to impact, further improving the protection effect on the hydraulic oil pipe.
[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
