Description

Technical Field

[0001] This utility model relates to the field of sliding contact line installation technology, and more specifically, to a sliding contact line installation cage. Background Technology

[0002] In electrical construction, after the steel structure of the crane beam and rails is installed but before the crane itself is installed, it is often necessary to install a sliding contact line bracket and a sliding contact line on the crane beam stiffener plate, located on the side of the crane maintenance cage current collector. The installation mainly includes the sliding contact line bracket, insulators, and the sliding contact line. The sliding contact line serves as the slide rail for the crane current collector, providing power to the crane during operation.

[0003] Considering that installing the conductor rail support and conductor rail involves high-altitude and hot work, workers typically use a homemade maintenance cage welded from round steel, suspended above the track. The cage is then secured to a railing or lifeline using ropes. Wearing safety harnesses and fall arrestors, workers climb down to the cage, lower a weight, and measure the installation of the conductor rail support and conductor rail. After welding one support, workers must climb back to the ground, untie the ropes, and tie it to the next support installation location, repeating this process. The spacing between supports is based on the crane beam stiffener spacing, generally around 1.5 meters. The materials used, welding quality, and load-bearing capacity of the homemade cage are unpredictable, and the frequent up-and-down movements pose significant safety hazards. Furthermore, the handling and securing of the cage is extremely tedious, time-consuming, and labor-intensive. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a sliding contact line installation cage to solve the problems of large safety hazards, cumbersome operation and time and labor cost in the existing installation of sliding contact line brackets and sliding contact lines.

[0005] The present invention adopts the following technical solution:

[0006] A sliding contact line installation cage includes a crane beam, a rail, and a cage body. The rail is installed on the top of the crane beam. Several sliding contact line brackets are installed on one side of the crane beam, and sliding contact lines are installed on the sliding contact line brackets. Two rail trolleys are provided on each side of the rail. The upper ends of every two rail trolleys are connected by connecting columns. The tops of the two connecting columns are connected to the top of the crane beam body. The cage body is also equipped with crane beam trolleys and a drive gear. The bottom of the crane beam trolleys contacts the top of the crane beam. The drive gear meshes with a driven gear. A driven shaft is installed at the center of the driven gear, and the other end of the driven shaft is connected to the center of the crane beam trolley.

[0007] Furthermore, it also includes railings, which are installed on top of the crane beam.

[0008] Furthermore, a drive shaft is installed at the center of the drive gear, the outer side of the drive shaft is connected to the crank, the other side of the drive shaft is installed on the gear frame, the gear frame is installed on the cage body, the other end of the crank is connected to the connecting rod, the bottom of the connecting rod is connected to the foot pedal, and a spring is installed between the bottom of the foot pedal and the cage body.

[0009] Furthermore, the connecting rod is equipped with markings.

[0010] Furthermore, the cage body includes a body frame, a cage bottom plate, and a cage top plate. The cage bottom plate is installed at the bottom of the body frame. The top of the body frame is provided with two connecting rods located at the top of the crane beam.

[0014] Beneficial effects

[0015] This utility model features a crank-rocker structure consisting of a foot pedal, spring, connecting rod, crank, and gear frame. Stepping on the foot pedal causes the driving and driven gears to rotate reciprocally. The connecting rod has markings to facilitate the measurement of the relative dimensions with the track during bracket installation, making operation convenient, greatly improving work efficiency, and avoiding frequent handling of the hoist cage and dimensional measurements.

[0016] This invention utilizes a gear transmission structure consisting of a driving gear, a driven gear, a gear frame, and a crank. The large gear drives the small gear, resulting in a more labor-saving and reliable transmission. A brake plate, with one smooth side and one sharp side, is incorporated, using gravity to ensure the driven gear rotates only in one direction, achieving a braking effect and enhancing safety and stability.

[0017] This invention features a stable triangular structure composed of a track trolley and a crane beam trolley, which allows the cage to stand firmly on the crane beam track and above the crane beam. The driven gear rotation enables the cage to slide smoothly on the crane beam and track, making it more stable and reliable. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] As shown in the figure, this utility model discloses a sliding contact line installation cage, including a crane beam 1, a track 2, and a cage body 3. The track 2 is installed on the top of the crane beam 1. Several sliding contact line brackets 4 are installed on one side of the crane beam 1. Sliding contact lines 5 are installed on the sliding contact line brackets 4. Two track trolleys 6 are respectively provided on both sides of the track 2. The upper ends of every two track trolleys 6 are connected by connecting columns 7. The tops of the two connecting columns 7 are connected to the top of the crane beam body 3. The cage body 3 is also equipped with a crane beam trolley 8 and a drive gear 9. The bottom of the crane beam trolley 8 contacts the top of the crane beam 1. The drive gear 9 meshes with a driven gear 10. A driven shaft 11 is installed at the center of the driven gear 10. The other end of the driven shaft 11 is connected to the center of the crane beam trolley 8.

[0026] This invention uses an active gear to drive a driven gear to reciprocate, which facilitates operation, greatly improves work efficiency, and avoids frequent handling of the cage and dimensional measurement.

[0027] The diameter of the driving gear 9 is larger than that of the driven gear 10. The large-diameter driving gear 9 drives the small-diameter driven gear 10 to rotate, which is more labor-saving and reliable.

[0028] In one embodiment of this utility model, a railing 12 is also included, which is installed on the top of the crane beam 1. The railing 12 serves a protective function.

[0029] In one embodiment of this utility model, a drive shaft 13 is installed at the center of the drive gear 9. The outer side of the drive shaft 13 is connected to the crank 14. The other side of the drive shaft 13 is installed on the gear frame 15. The gear frame 15 is installed on the cage body 3. The other end of the crank 14 is connected to the connecting rod 16. The bottom of the connecting rod 16 is connected to the foot pedal 17. A spring 18 is installed between the bottom of the foot pedal 17 and the cage body 3.

[0030] This invention features a crank-rocker structure comprised of a foot pedal 17, a spring 18, a connecting rod 16, a crank 14, and a gear frame 15. Stepping on the foot pedal 17 drives the drive gear 9 to rotate, providing convenience and saving effort. The spring 18 serves a resetting function.

[0031] In one embodiment of this utility model, the connecting rod 16 is provided with a scale 161. The scale 161 facilitates the measurement of the relative dimensions with the track 2 when installing the sliding contact line bracket 4.

[0032] In one embodiment of this utility model, the cage body 3 includes a body frame 31, a cage bottom plate 32, and a cage top plate 33. The cage bottom plate 32 is installed at the bottom of the body frame 31. The top of the body frame 31 is provided with two connecting rods 34 located at the upper end of the crane beam. A crane beam trolley mounting bracket 35 is installed at the lower end of one of the connecting rods 34, and a crane beam trolley 8 is installed at the crane beam trolley mounting bracket 35. The operator stands on the crane beam bottom plate 32 to perform the operation.

[0033] In one embodiment of this utility model, another connecting rod 34 is equipped with a support rod 36, and the bottom of the support rod 36 is connected to the middle of the connecting column 7.

[0034] In one embodiment of this utility model, a support plate 19 is fitted onto the drive shaft 13, and a brake plate 20 is installed at the other end of the support plate 19. One end of the brake plate 20 is a tip 21, which is located between two teeth of the driven gear 10.

[0035] Due to gravity, the brake plate 20 is located between the two teeth of the driven gear 10. When moving in one direction, the teeth of the driven gear 10 will push the brake plate 20 upward to achieve unidirectional rotation. When moving in the opposite direction, the teeth of the driven gear 10 cannot push the brake plate 20 upward, so the brake plate 20 is always stuck between the two teeth of the driven gear 10, thus playing a braking role.

[0036] This invention, by incorporating a brake plate 20, ensures that the driven gear 10 can only rotate in one direction. Reverse rotation is prevented by the brake plate 20, as it applies pressure to the gear. Here, "directional rotation" refers to rotation opposite to unidirectional rotation. The design of the brake plate 20 ensures safe and reliable rotation of the driven gear 10.

[0037] In one embodiment of this utility model, the sliding contact line 5 is arranged horizontally, and each sliding contact line 5 is placed on multiple sliding contact line supports 4.

[0038] The present invention has one crane beam trolley 8 and four track trolleys 6. The two track trolleys 6 close to the crane beam trolley 8 and the crane beam trolley 8 form an isosceles triangle, which is structurally stable. This allows the cage to stand firmly on the crane beam track and above the crane beam. When the driven gear rotates, it can drive the cage body 3 to slide smoothly on the crane beam and track.

[0039] The track 2 here is an I-beam, and the track trolleys 6 are all equipped with pulleys. The four track trolleys 6 are locked on both sides of the web of the track 2. During operation, the track trolleys 6 will not fall off the track 2.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
