Description

Technical Field

[0001] The present invention relates to the technical field of ladder vehicles, and more particularly to an anti-slip ladder vehicle moving mechanism and a ladder vehicle. Background Art

[0002] A ladder truck is a simple tool essential for overhead construction, inspection, and maintenance. When working at height, a ladder truck serves as a mobile construction platform for ease of mobility. The stability of a ladder truck directly impacts the safety of workers working at height, as well as those nearby and equipment.

[0003] Because the track surface of a ladder truck is smooth and has a low friction coefficient, it can easily cause the truck to wobble if no braking measures are taken during construction, affecting construction quality. Even more seriously, when the ladder truck is operating on a slope, it can cause a "slip" accident, which can easily cause personal injury.

[0004] Currently, to ensure the stability of ladder vehicles, manual support and fixation are primarily relied upon. Generally, mandatory regulations require that a ladder vehicle be pushed and fixed by no fewer than four people, with no more than two people on the platform. The stability of a ladder vehicle is primarily determined by track conditions (whether it is properly adjusted, located on steep slopes, curves, or in station bottlenecks), operator configuration, and safety awareness. The existing manual support and fixation method for ladder vehicles incurs significant labor costs. Furthermore, if construction personnel are insufficient, the number of personnel required to push and fix the vehicle may be reduced, increasing the likelihood of tipping and derailment accidents, resulting in personal injury and property damage.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] A ladder truck is a simple tool essential for overhead construction, inspection, and maintenance. When working at height, a ladder truck serves as a mobile construction platform for ease of mobility. The stability of a ladder truck directly impacts the safety of workers working at height, as well as those nearby and equipment.

[0037] At present, the operation of ladder trucks mainly relies on manual support and fixation. The existing manual support and fixation method of ladder trucks requires a lot of manpower costs. In addition, when there is a shortage of construction workers, the number of people responsible for pushing and fixing the ladder trucks may be reduced, resulting in an increased probability of tipping and derailment accidents, causing personal injury and property loss.

[0038] The traditional ladder car moving mechanism uses ladder wheels, such as Figure 1 As shown, due to the smooth surface of the ladder track, the friction coefficient between the ladder wheels and the track is low. If no braking measures are taken during construction, the ladder truck will easily shake, affecting the construction quality. In more serious cases, when the ladder truck is operating on a slope, it may cause the ladder truck to "slip", which can easily cause personal injury.

[0039] In view of the above reasons, the embodiments of the present invention are intended to design a ladder trolley moving mechanism and ladder trolley that is simple in structure, easy to manufacture, low in cost, and can prevent slipping and overturning. The development of this tool greatly improves the stability and safety of the ladder trolley. The following is a detailed description of multiple embodiments with reference to the accompanying drawings.

[0040] Figure 2 The structural diagram of the anti-skid ladder vehicle moving mechanism provided by the embodiment of the present invention is as follows: Figure 2 As shown, the anti-skid ladder vehicle moving mechanism includes an axle clamping assembly 1, a wheel mounting seat 2, a rolling load-bearing wheel assembly 3 and an anti-skid wedge 5;

[0041] The rolling load-bearing wheel assembly 3 is fixedly installed in the wheel mounting seat 2, and the rolling load-bearing wheel assembly 3 is rollingly connected to the upper end surface of the ladder track 6. The rolling load-bearing wheel assembly 3 includes a plurality of rolling load-bearing wheels arranged along the length direction of the ladder track 6. Figure 1 In this embodiment, the number of rolling load-bearing wheels is two; the ladder car track 6 in this embodiment can be made of steel rails.

[0042] The axle clamping assembly 1 is mounted on the wheel mounting seat 2 and is used to fix the axle of the ladder truck;

[0043] The anti-skid wedge 5 is installed in the wheel mounting seat 2, and the anti-skid wedge 5 clamps the rolling load-bearing wheel assembly 5 to stop the rolling load-bearing wheel assembly; the anti-skid wedge 5 is detachable to release the clamping of the rolling load-bearing wheel assembly 5.

[0044] Specifically, the anti-skid ladder vehicle moving mechanism has two working states during use, one is a moving working state, and the other is an anti-skid working state. Figure 2 The anti-skid ladder trolley moving mechanism shown is in a moving working state. At this time, the ladder trolley axle is fixed by the axle clamping assembly 1, and the rolling load-bearing wheel assembly 3 rolls on the end surface of the ladder trolley track.

[0045] When the ladder truck needs to be stopped for construction, the anti-skid wedge 5 is installed in the wheel mounting seat. At this time, the anti-skid ladder truck moving mechanism is in the anti-skid working state. Figure 3 Schematic diagram of the anti-slip working state of the anti-slip ladder vehicle moving mechanism provided by the embodiment of the present invention; Figure 3 As shown in Figure 4(a), one end of the anti-skid wedge 5 is connected to the rolling load-bearing wheel. As shown in Figure 4(b), to match the cylindrical end surface of the rolling load-bearing wheel, the end surface of the anti-skid wedge 5 that contacts the rolling load-bearing wheel is designed as a concave arc end surface, so that the anti-skid wedge 5 and the rolling load-bearing wheel fit tightly together. The anti-skid wedge 5 clamps the rolling load-bearing wheel assembly to stop rolling, achieving the anti-skid function of the ladder truck.

[0046] It is understandable that the use of Figure 1 When the ladder wheels shown are used to move the ladder, in order to ensure the stability of the ladder, it generally requires no less than 4 people to push and fix the ladder during the moving process, which consumes a lot of manpower costs. Figure 1 Compared with the ladder wheels shown in the figure, the anti-skid ladder trolley moving mechanism provided by the embodiment of the present invention only requires two people to assist under the ladder trolley, which effectively reduces the labor cost, and can effectively stop the ladder trolley and prevent it from slipping, avoiding the ladder trolley from overturning and sliding accidents, and improving the reliability and safety of the ladder trolley.

[0047] Based on the above embodiments, Figure 2 and Figure 3As shown, the anti-skid ladder trolley moving mechanism also includes a clamping wheel assembly 4: the clamping wheel assembly 4 includes two pairs of clamping wheel devices, and the two pairs of clamping wheel devices are respectively installed on the wheel mounting seats 2 on both sides of the ladder trolley track 6, and the clamping wheel devices are rollingly connected to the side end faces of the ladder trolley track 6.

[0048] Specifically, two pairs of clamping wheel devices are respectively installed on the wheel mounting base 2 on both sides of the ladder track 6. The clamping wheel devices are in rolling connection with the side end faces of the ladder track 6. The clamping wheel devices are wrapped around the upper edge of the ladder track to prevent overturning. Figure 3 One side of the anti-skid wedge 5 is tightly engaged with the rolling load-bearing wheel assembly 4, and the other side of the anti-skid wedge 5 abuts against the clamping wheel device. The upper end of the anti-skid wedge 5 is limited by the wheel mounting seat 2. When the ladder truck needs to be stopped for construction, the anti-skid wedge 5 clamps the rolling load-bearing wheel assembly to stop the rolling of the rolling load-bearing wheel assembly, thereby stopping the ladder truck from skidding.

[0049] Figure 5 The structural diagram of the clamping wheel device provided in the embodiment of the present invention is shown in FIG. Figure 2 and Figure 5 Specifically, the clamping wheel device includes a clamping wheel cantilever 4-1 and a clamping wheel 4-2, one end of the clamping wheel cantilever is fixedly mounted on the wheel mounting seat 2, and the other end of the clamping wheel cantilever is rotatably connected to the clamping wheel 4-2.

[0050] The clamping wheel 4-2 is provided with clamping wheel limiters at both axial ends thereof, which can limit the movement track of the clamping wheel so that the clamping wheel 4-2 rolls along the upper edge of the ladder track, thereby improving the stability of the clamping wheel device.

[0051] The clamping wheel cantilever 4-1 can be connected to the wheel mounting seat 2 through a pin, so that one end of the clamping wheel device is stably fixed on the wheel mounting seat 2. The clamping wheel 4-2 is processed according to the geometric shape of the upper part of the ladder car track, fully wrapping the upper edge of the rail, and playing a role in preventing the ladder car from overturning during operation.

[0052] Figure 6 A schematic diagram of the structure of the axle clamping assembly provided in an embodiment of the present invention is shown in FIG. Figure 6 As shown, the axle clamping assembly 1 includes a support shaft 1-1, a clamping support 1-2 and a cover plate 1-3;

[0053] The upper end of the support shaft 1-1 is fixedly connected to a clamping support 1-2, and the lower end of the support shaft 1-1 is fixedly mounted on the wheel mounting seat 2. The support shaft 1-1 is connected to the wheel mounting seat 2 to transfer the load above the axle clamping assembly 1 to the rolling load-bearing wheel assembly 3, thereby improving the stability of the ladder truck.

[0054] Reference Figure 6The clamping support 1-2 and the cover plate 1-3 are hinged. The upper surface of the clamping support 1-2 is provided with a first arc groove, and the lower surface of the cover plate 1-3 is provided with a second arc groove. The first arc groove and the second arc groove cooperate to clamp the ladder trolley axle to achieve a fixed connection between the anti-slip ladder trolley moving mechanism and the ladder trolley.

Figure 7 As shown, the rolling load-bearing wheel assembly 3 includes a plurality of rolling load-bearing wheels 3-1 arranged along the length direction of the ladder vehicle track 6. In this embodiment, two rolling load-bearing wheels 3-1 are arranged along the length direction of the ladder vehicle track 6. Figure 7 The rolling load-bearing wheel 3-1 includes a wheel body and an axle 3-2. The axle extends through the axial center of the wheel body to the outside of the wheel mounting seat 2. Load-bearing wheel limiters 3-3 are provided at both axial ends of the wheel body. The wheel body and wheel disc are disposed within the wheel mounting seat 2. The load-bearing wheel limiters 3-3 can limit the movement trajectory of the rolling load-bearing wheel 3-1, allowing the rolling load-bearing wheel 3-1 to roll along the upper end surface of the ladder vehicle track, thereby improving the stability of the rolling load-bearing wheel assembly.

[0056] Connecting plates are installed at both axial ends of the wheel axle, and the rolling load-bearing wheel 3 - 1 is fixedly installed in the wheel mounting seat 2 through the connecting plates.

[0057] Figure 8 A schematic diagram of the structure of the wheel mounting base provided in an embodiment of the present invention is shown in FIG.

A connecting groove is provided at the upper end of the support connecting block 2-1, into which the support shaft 1-1 of the axle clamping assembly 1 is affixed. The support shaft 1-1 is fixedly connected to the support connecting block 2-1 of the wheel mounting base 2, enabling the load above the axle clamping assembly 1 to be transferred to the rolling load-bearing wheel assembly 3, thereby improving the stability of the ladder vehicle.

[0058] The wheel mounting seat 2 is further provided with a first mounting portion 2-2 and a second mounting portion 2-3, wherein the first mounting portion is used to mount the rolling load-bearing wheel assembly 3, and the second mounting portion is used to mount the clamping wheel assembly 4. Figure 2 、 Figure 5 and Figure 6 , a plurality of screw holes 3-5 are provided on the connecting plate 3-4 of the rolling load-bearing wheel 3-1, and screw holes of the same diameter are provided at corresponding positions of the first mounting portion of the wheel mounting seat 2, and the connecting plate of the rolling load-bearing wheel 3-1 is connected to the wheel mounting seat 2 by screws. Figure 5 and Figure 8 The clamping wheel cantilever 4-1 can be fixedly connected to the second connecting portion of the wheel mounting seat 2 through a pin.

[0059] In an optional embodiment, the method of using the anti-skid ladder vehicle moving mechanism is as follows:

[0060] ①Open the clamping wheel device and install the four anti-skid ladder moving mechanisms on the ends of the two ladder axles of the ladder chassis.

[0061] ② Place the assembled ladder car on the ladder car track and move it. At this time, the anti-skid wedge 5 is not installed.

[0062] ③ Close the clamping wheel device and install the locking pin to close the clamping wheel device 4 and put it into working state.

[0063] ④ When the ladder truck needs to be stationary, install the anti-skid wedge 5 in the wheel mounting seat 2 to put the ladder truck in an anti-skid working state.

[0064] ⑤ After use, pull out the locking pin, open the clamping wheel device, and move the ladder car out of the ladder car track.

[0065] Figure 9 A schematic diagram of the structure of a ladder truck provided by an embodiment of the present invention is shown in FIG. Figure 9 As shown, the ladder truck includes a ladder truck chassis 7, a ladder truck bracket 8 fixedly mounted on the ladder truck chassis, and the anti-slip ladder truck moving mechanism 10 as described in the above embodiments; a working platform is fixedly mounted on the top of the ladder truck bracket 8.

[0066] Specifically, the ladder trolley chassis 7 includes two ladder trolley axles 9 perpendicular to the ladder trolley track, and two longitudinal beams 11 parallel to the ladder trolley track 6 and connected to the ladder trolley axles 9; the axial ends of each ladder trolley axle 9 are respectively fixedly connected with the anti-skid ladder trolley moving mechanism 10, and the anti-skid ladder trolley moving mechanism 10 is in rolling cooperation with the ladder trolley track 6.

[0067] The anti-slip ladder vehicle moving mechanism and ladder vehicle provided by the embodiments of the present invention have the following advantages over the prior art:

[0068] (1) When the ladder car is in working state, whether it is stationary or moving, the anti-skid ladder car moving mechanism always tightly covers the upper edge of the rail, which greatly improves the safety of the ladder car and avoids the ladder car overturning and sliding accidents.

[0069] (2) Considering that a large number of ladder trucks have been put into use, the anti-skid ladder truck moving mechanism provided in the embodiment of the present invention only improves and optimizes the ladder wheels, and the other parts of the ladder truck can still be used, saving the cost of ladder truck improvement.

[0070] (3) By Figure 1 The existing ladder car moving mechanism shown is Figure 2Comparing the anti-slip ladder trolley moving mechanism provided by the present invention with the existing one, it is clear that the friction coefficient between the existing ladder wheels and the ladder track surface is low. Without a locking mechanism, the ladder trolley can easily wobble during construction, requiring four workers to secure it with their hands. The anti-slip ladder trolley moving mechanism provided by the present invention, however, uses rolling load-bearing wheels and clamping wheels that fully wrap around the upper edge of the ladder track, forming a temporary rigid connection with the ladder track, resulting in better working conditions.

[0071] (4) Figure 1 After the existing ladder trolley moving mechanism (ladder wheels) shown is replaced with the anti-slip ladder trolley moving mechanism provided by the embodiment of the present invention, the number of auxiliary personnel under the ladder trolley can be reduced from 4 to 2, effectively reducing labor costs, and can effectively stop the ladder trolley from slipping, thereby improving the reliability and safety of the ladder trolley.

[0072] (5) The anti-skid ladder vehicle moving mechanism provided by the embodiment of the present invention has a simple structure, is easy to manufacture, has a low cost, and is easy to promote and apply.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
