Description

Technical Field

[0001] This utility model relates to the field of train car ladder technology, specifically a train car ladder with a reinforced structure. Background Technology

[0002] The bulk cargo terminal uses trains to transport materials. Before loading the train cars, workers need to carry tools to enter the cars and manually lay and seal any leaks. Currently, there are two ways for workers to enter the cars. The first is to open the car door and enter the car, which is quite troublesome. The second is to climb up to the top of the car edge by hand or using a traditional bamboo ladder and jump down. The surface of the traditional bamboo ladder is relatively smooth, and it is easy to slip when leaning against the edge of the car. In addition, the crossbeams of the ladder are not securely assembled, which poses a certain danger in the long term.

[0003] To overcome the above defects, in the prior art 1 (Chinese patent application number CN202323348928.2, application date 2023-12-08), a type of anti-falling safety ladder is provided with a support and stabilization mechanism. When the bottom of the fixed block is in contact with the top surface of the train, the contact block is squeezed, which causes the connecting rack to drive the meshing connecting gear to rotate. This allows the bidirectional threaded rod to drive the extension block to slide inside the fixed block through the limiting slider, which increases the contact area between the fixed block and the top surface and prevents the phenomenon of falling off.

[0004] While existing technology can fix the hanging position of the ladder to prevent it from loosening and falling off during use, the ladder is usually used with trains of different sizes. The ladder does not have an adjustment mechanism to adjust the size of the hanging position, which reduces its applicability.

[0005] Therefore, we proposed that a train ladder with a reinforced structure can effectively solve the above problems. Summary of the Invention

[0006] The purpose of this utility model is to provide a train card hanging ladder with a reinforced structure to solve the problem mentioned in the background art that the current hanging ladders on the market are usually used to hang with trains of different sizes, and the hanging ladders do not have an adjustment mechanism to adjust the hanging size of the ladder, which reduces the applicability of the hanging ladder.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a train ladder with a reinforced structure, comprising a steel pipe frame and a row of ladder crossbars, wherein the row of ladder crossbars is equally spaced on the inner side of the steel pipe frame, and the top of the steel pipe frame is inverted "L" shape;

[0008] Positioning frames are installed at both ends of the bottom of the steel pipe frame, and the two positioning frames are of the same length. A limit frame is slidably installed through a slot at the top of the steel pipe frame.

[0009] The limiting frame has slots at both ends for sliding installation of limiting blocks, and the two limiting blocks are symmetrically arranged about the vertical center line of the limiting frame. The outer ends of the two limiting blocks extend through to the outer sides of the top two ends of the steel pipe frame.

[0010] Preferably, a row of limiting grooves is provided at both ends of the top of the steel pipe frame, and the two rows of limiting grooves are equally spaced, and two limiting blocks are slidably connected through the interior of the two rows of limiting grooves.

[0011] Preferably, the two ends of the limiting frame are provided with first return springs, and the two first return springs have the same structure, and the outer ends of the two first return springs are connected to limiting blocks.

[0012] Preferably, the upper two sides of the limiting frame have slots through which pull rods are slidably installed by compression springs, and the outer ends of the two pull rods are connected to pull ropes, and the outer ends of the two pull ropes are connected to the limiting blocks by guide wheels.

[0013] Preferably, a row of extension rods is slidably installed through slots on both sides of the rear end of the steel pipe frame via a second reset spring, and the outer ends of the two rows of extension rods are connected to movable plates, and the inner ends of the two movable plates correspond to the steel pipe frame.

[0014] Preferably, a row of racks is provided at the bottom of the left-end row of extension rods, and a rotating gear is meshed at the bottom of the racks. The rotating gear is rotatably installed inside the left side of the steel pipe frame.

[0015] Preferably, a row of rotating shafts is rotatably installed in the internal slots of a row of ladder crossbars, and a row of rotating gears is connected through the left end of the row of rotating shafts. A row of striking blocks is installed through the outer end of the row of rotating shafts at equal intervals, and a row of vibrating blocks is corresponding to the outer end of the row of striking blocks. At the same time, a row of vibrating blocks is arranged at equal intervals inside the row of ladder crossbars.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] A limiting frame is installed by slotting the top inner side of the steel pipe frame and sliding it through. Then, slots are made at both ends of the limiting frame and limiting blocks are slidably installed through the first return springs. The two limiting blocks can be automatically popped into a row of limiting slots on both sides of the top of the steel pipe frame by the elastic force of the two first return springs. This can fix the sliding limiting frame and prevent the limiting frame from being misaligned or shifted during use, thus improving the safety of the hanging ladder.

[0018] Furthermore, when it is necessary to adjust the hanging size of the ladder, simply press the two pull rods manually to drive the two pull ropes through the guide wheels to pull the two limit blocks to retract and move, so that the two limit blocks are separated from the limit groove. Then the position of the limit frame can be adjusted by length. Finally, the two first return springs automatically pop the two limit blocks to the outside of both ends of the steel pipe frame by their own elasticity. The operation is more time-saving and labor-saving, and improves the applicability of the ladder.

[0019] Furthermore, by utilizing the compression springs installed at both ends of the internal slot of the limiting frame, the elastic force of the two compression springs can elastically reset the two pulled rods after pressing and moving, so as to facilitate repeated use later.

[0020] The system is equipped with a rotating shaft. A row of rotating shafts is installed in the grooves inside the row of ladder crossbars. A row of striking blocks is installed through the outer end of the rotating shafts. While the rotating shafts drive the row of striking blocks to rotate, they reciprocate and vibrate the row of vibrating blocks inside the row of ladder crossbars. This reciprocating vibration removes dust and impurities adhering to the surface of the ladder crossbars, preventing dust and impurities from sticking to the surface of the ladder crossbars and affecting subsequent climbing use, thus improving practicality.

[0021] Furthermore, by utilizing slots at both ends of the steel pipe frame and a row of extension rods that slide through and connect movable plates, workers can manually press the two movable plates while climbing the ladder, causing the two rows of extension rods to extend through to both ends of the steel pipe frame. At this time, a row of racks at the bottom of the two rows of extension rods will simultaneously drive a row of rotating gears to rotate. Subsequently, the rotating gears will simultaneously drive a row of rotating shafts to rotate. Finally, the elastic force of a second set of return springs can elastically reset the position of the movable plates after pressing and moving them, making the operation more time-saving and labor-saving.

[0029] 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.

[0030] This utility model provides the following technical solution:

[0031] Example 1: To address the problem that existing hanging ladders on the market are typically designed for use with trains of varying sizes, and lack an adjustment mechanism to regulate their mounting dimensions, thus reducing their applicability, the following solution is disclosed:

[0032] The steel pipe frame 1 and a row of ladder crossbars 2 are arranged at equal intervals on the inner side of the steel pipe frame 1, and the top of the steel pipe frame 1 is inverted "L" shape.

[0033] Positioning frames 3 are installed at both ends of the bottom of the steel pipe frame 1, and the two positioning frames 3 are of the same length. A limit frame 4 is installed through a slot on the top of the steel pipe frame 1.

[0034] The two ends of the inner end of the limiting frame 4 are slotted and slidably installed with limiting blocks 9. The two limiting blocks 9 are symmetrically arranged about the vertical center line of the limiting frame 4, and the outer ends of the two limiting blocks 9 extend through to the outer sides of the top two ends of the steel pipe frame 1.

[0035] A row of limiting grooves 10 is opened at both ends of the top of the steel pipe frame 1, and the two rows of limiting grooves 10 are equally spaced. Two limiting blocks 9 are slidably connected through the interior of the two rows of limiting grooves 10.

[0036] The two ends of the limit frame 4 are slotted and provided with first reset springs 11, and the two first reset springs 11 have the same structure, and the outer ends of the two first reset springs 11 are connected to limit blocks 9.

[0037] The upper sides of the limit frame 4 have slots through which pull rods 7 are slidably installed via compression springs 8, and the outer ends of the two pull rods 7 are connected to pull ropes 12, and the outer ends of the two pull ropes 12 are connected to limit blocks 9 via guide wheels.

[0038] like Figures 1-4 As shown, when the positioning distance of the ladder needs to be adjusted, simply press the two pull rods 7 manually to drive the two pull ropes 12 to pull the two limit blocks 9 simultaneously through the guide wheels, causing them to retract and move. This separates the two limit blocks 9 from the steel pipe frame 1, allowing the positioning distance of the limit frame 4 to be adjusted. Once the appropriate position is reached, the two first return springs 11 will use their own elastic force to elastically reset the position of the two retracted limit blocks 9, thus popping the two limit blocks 9 out to the outside of the two rows of limit slots 10. This allows the position of the limit frame 4 to be adjusted, making the operation more time-saving and labor-saving. Finally, the two compression springs 8 can use their own elastic force to compress and reset the position of the two pressed and moved pull rods 7, facilitating repeated use and improving the applicability of the hanging ladder.

[0039] Example 2 differs from Example 1 in that it allows for the reciprocating vibration cleaning of dust and impurities adhering to the surface of a row of ladder crossbars 2, preventing dust and impurities from sticking to the surface of the ladder crossbars 2 and affecting subsequent climbing use. The following is disclosed:

[0040] The steel pipe frame 1 has slots on both sides of its rear end, through which a row of extension rods 5 are slidably installed. The outer ends of the two rows of extension rods 5 are connected to movable plates 6, and the inner ends of the two movable plates 6 correspond to the steel pipe frame 1.

[0041] A row of racks 14 is provided at the bottom of the left end of the row of extension rods 5, and a rotating gear 15 is meshed at the bottom of the row of racks 14. At the same time, the row of rotating gears 15 is rotatably installed inside the left side of the steel pipe frame 1.

[0042] A row of ladder crossbars 2 has a slotted interior on which a row of rotating shafts 16 are rotatably installed. A row of rotating gears 15 are connected through the left end of the row of rotating shafts 16. A row of striking blocks 17 are installed through the outer end of the row of rotating shafts 16 at equal intervals. A row of vibrating blocks 18 are located at the outer end of the row of striking blocks 17. At the same time, a row of vibrating blocks 18 are arranged at equal intervals inside the row of ladder crossbars 2.

[0043] like Figures 1-6As shown, when workers climb the ladder, they manually grasp the movable plate 6 and retract it to the outside of the steel pipe frame 1. At this time, a row of extension rods 5 connected to the inner end of the left movable plate 6 will drive a row of rotating gears 15 through a row of racks 14 to rotate the shaft 16. Subsequently, a row of striking blocks 17 set at the outer end of the shaft 16 will simultaneously strike and vibrate a row of vibrating blocks 18 set inside the ladder crossbar 2. This will vibrate and remove dust and impurities adhering to the surface of the ladder crossbar 2, preventing dust and impurities from sticking to the surface of the ladder crossbar 2 and affecting subsequent climbing. Finally, the elastic force of a row of second return springs 13 can elastically reset the position of the row of extended rods 5 after pressing and retracting, so as to facilitate repeated pressing and use of the movable plate 6 in the future, making the operation more time-saving and labor-saving.
