Description

Technical Field

[0001] This application relates to the field of forklift structure technology, and in particular to a forklift overhead guard. Background Technology

[0002] Forklifts are various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. They are one of the most commonly used handling vehicles today. They are relatively small and can enter ship holds, truck compartments, and containers to load, unload, and handle palletized goods, making them widely used.

[0003] Existing forklifts are equipped with overhead guards, forming a cab between the overhead guard and the vehicle body. To provide good visibility, the top surface of the overhead guard is open, which means that when the forklift is operating outdoors in rainy weather, rainwater can easily enter the cab through the open parts of the overhead guard, wetting the forklift driver's clothes and causing great discomfort to the driver. Therefore, further improvements are needed. Summary of the Invention

[0004] To address the problem of inconvenience in using forklifts in rainy weather, this application provides a forklift overhead guard.

[0005] The forklift overhead guard provided in this application adopts the following technical solution: A forklift overhead guard includes a canopy and multiple support columns connected to the canopy. The support columns are used for mounting on the body of a forklift. The canopy includes a pair of parallel longitudinal beams and several crossbeams fixedly connected between the two longitudinal beams. A baffle is provided between two adjacent crossbeams. Multiple baffles are provided and spaced apart along the length direction of the crossbeams. A rotating shaft rotatably connected to the crossbeam protrudes from the end face of the baffle. The axis of the rotating shaft is parallel to the length direction of the longitudinal beams. The crossbeam is provided with a conversion mechanism for driving the multiple rotating shafts to rotate. When the baffle is rotated to a horizontal state, the sides of two adjacent baffles are in contact with each other.

[0006] By adopting the above technical solution, under normal conditions, multiple baffles are in a vertical state, forming a large ventilation space between adjacent baffles, increasing the ventilation of the cab. When encountering rain during outdoor operations, the conversion mechanism drives multiple shafts to rotate 90°, thereby switching the baffles to a horizontal state. The sides of adjacent baffles fit together, thus sealing the ventilation space and providing a shielding effect for the inside of the forklift, effectively reducing the possibility of rainwater falling into the cab and reducing discomfort for the forklift driver when operating in rainy weather.

[0007] Preferably, the sidewall of the baffle is provided with an elastically provided sealing strip, and when the baffle is in a horizontal state, the sealing strips on two adjacent baffles abut against each other.

[0008] By adopting the above technical solution, a sealing strip is added to the side wall of the baffle. When the baffle is in a horizontal state, the sealing strips on the two adjacent baffles press against each other, which effectively improves the sealing performance of the joint between the two adjacent baffles in a horizontal state and reduces the possibility of rainwater seeping in from the joint between the two baffles.

[0009] Preferably, the side wall of the baffle is provided with a mounting groove, and one side of the sealing strip is provided with a mounting strip that is embedded in the mounting groove.

[0010] By adopting the above technical solution, an installation slot and an installation strip are added to enable the sealing strip to be snapped into the baffle.

[0011] Preferably, when the baffle is in a horizontal state, one of the two sealing strips that abut against each other has a sealing groove on its outer side wall, and the other sealing strip has a sealing strip that is engaged with the sealing groove on its outer side wall.

[0012] By adopting the above technical solution, a sealing groove and a sealing strip are added between two adjacent sealing strips. The sealing strip is engaged in the sealing groove, which increases the contact area between the two sealing strips, thereby improving the sealing performance between the two sealing strips.

[0013] Preferably, the baffle located at the outermost edge is in a horizontal state and has a gap between it and the longitudinal beam to form a drainage channel.

[0014] By adopting the above technical solution, rainwater falls onto the roof baffle and is discharged from the roof through the drainage channel, reducing the possibility of water accumulation on the roof.

[0015] Preferably, the crossbeam has a mounting cavity, the end of the rotating shaft extends into the mounting cavity, and the conversion mechanism includes a transmission wheel built into the mounting cavity and coaxially fixedly sleeved on the rotating shaft, a synchronous belt wound between two adjacent transmission wheels, and a first driving member for driving one of the rotating shafts.

[0016] By adopting the above technical solution, one of the rotating shafts is driven to rotate by the first driving component, thereby driving the adjacent rotating shafts to rotate synchronously through the transmission wheel and the synchronous belt. This process is repeated to achieve synchronous rotation of multiple rotating shafts, thereby enabling synchronous rotation and switching of multiple baffles.

[0017] Preferably, the baffle is a transparent plate, and a storage groove is provided on the inner side wall of one of the longitudinal beams. The storage groove is located between two adjacent crossbeams, and a scraper is slidably connected between the two adjacent crossbeams. Under normal conditions, the scraper is built into the storage groove, and the lower end face of the scraper is used to abut against the upper end face of the baffle in a horizontal state. The longitudinal beam is provided with a driving mechanism to drive the scraper to slide back and forth along the length direction of the crossbeam.

[0018] By adopting the above technical solution, under normal circumstances, the scraper is built into the storage groove to avoid interference between the baffle and the scraper. When encountering rain during outdoor operations, after the baffle switches to a horizontal state, the scraper is driven by the drive mechanism to perform reciprocating sliding motion. On the one hand, it pushes the rainwater on the baffle towards the edge of the roof, accelerating the rainwater discharge speed. On the other hand, it scrapes away the rainwater and dust and other debris adhering to the baffle, improving the cleanliness of the baffle surface and providing good visibility, making it easier for the driver in the cab to observe the working conditions above the forklift through the baffle.

[0019] Preferably, the inner sidewall of the crossbeam is provided with an upper sliding groove above the rotating shaft and a lower sliding groove below the rotating shaft along the length direction. The upper sliding groove is connected to the receiving groove. The scraper protrudes and is fixed with a slider that is slidably connected to the upper sliding groove. The driving mechanism includes a pair of rollers that are rotatably connected to the outer sidewall of the longitudinal beam, a transmission belt that passes through the longitudinal beam and is wound around the rollers, and a second driving member that drives the rollers to rotate. The two ends of the transmission belt are fixedly connected to the two sidewalls of the slider, respectively. The upper layer of the transmission belt is built into the upper sliding groove, and the lower layer of the transmission belt is built into the lower sliding groove.

[0020] By adopting the above technical solution, the roller is driven to rotate by the second driving component, thereby driving the slider to slide in the upper sliding groove through the transmission belt, thus realizing the sliding movement of the scraper. The addition of the upper and lower sliding grooves avoids interference between the baffle and the transmission belt.

[0021] Preferably, the lower part of the scraper is provided with a scraper strip that abuts against the upper surface of the baffle, and the scraper strip is elastically arranged.

[0022] By adopting the above technical solution, the scraper is set elastically, which effectively reduces the possibility of rigid contact between the scraper and the baffle, and reduces the possibility of the baffle being scratched.

[0023] Preferably, the scraper has a flow channel, and the lower end face of the scraper has an outlet hole communicating with the flow channel. The scraper strip is a sponge strip that covers the outlet hole. A tube communicating with the flow channel is fixedly connected to the side of the scraper away from the collection tank. Another longitudinal beam is fixedly connected to a storage box containing cleaning fluid. The storage box is provided with a flow pipe that is fixedly inserted through the longitudinal beam and extends out of the inner wall of the longitudinal beam. The flow pipe is provided with a one-way sealing plate that normally closes its opening. Multiple one-way sealing plates are provided and distributed around the circumference of the flow pipe. The one-way sealing plates are elastically arranged. When the tube is slidably inserted into the flow pipe, the end of the tube abuts against the one-way sealing plate, forcing the one-way sealing plate to bend and deform, thereby making the flow pipe and the tube communicate.

[0024] By adopting the above technical solution, under normal conditions, the one-way sealing plate in the flow tube seals the opening of the flow tube, effectively reducing the possibility of the cleaning fluid in the storage box leaking out of the flow tube. During the cleaning operation of the scraper on the upper surface of the baffle, the scraper slides towards the longitudinal beam containing the storage box, and when the insertion tube slides into the flow tube, the end of the insertion tube abuts against the one-way sealing plate, forcing the one-way sealing plate to bend and deform, thereby connecting the flow tube and the insertion tube. The cleaning fluid in the storage box flows into the flow channel through the flow tube and the insertion tube in sequence, and after being soaked in the sponge strip through the outlet hole, when the scraper slides in the opposite direction, the sponge strip soaked in cleaning fluid cleans the baffle, thereby improving the cleaning effect on the upper surface of the baffle. After the insertion tube is removed from the flow tube, the one-way sealing plate elastically resets.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Under normal conditions, multiple baffles are in a vertical position, forming a large ventilation space between adjacent baffles, increasing the ventilation of the cab. When encountering rain during outdoor operations, the conversion mechanism drives multiple shafts to rotate 90°, thereby switching the baffles to a horizontal position. The sides of adjacent baffles fit together, thus sealing the ventilation space and providing a shielding effect for the inside of the forklift, effectively reducing the possibility of rainwater falling into the cab and reducing discomfort for the forklift driver when operating in rainy weather. 2. Under normal circumstances, the scraper is built into the storage groove to avoid interference between the baffle and the scraper. When encountering rain during outdoor operations, the baffle switches to a horizontal position, and the scraper is driven by the drive mechanism to perform reciprocating sliding motion. On the one hand, it pushes the rainwater on the baffle towards the edge of the roof, speeding up the rainwater discharge. On the other hand, it scrapes away the rainwater and dust and other debris adhering to the baffle, improving the cleanliness of the baffle surface and providing good visibility, making it easier for the driver in the cab to observe the working conditions above the forklift through the baffle. 3. Under normal conditions, the one-way sealing plate inside the flow tube seals the opening of the flow tube, effectively reducing the possibility of cleaning fluid leaking from the flow tube into the storage box. During the cleaning operation of the scraper on the upper surface of the baffle, the scraper slides towards the longitudinal beam containing the storage box, and when the insertion tube is inserted into the flow tube, the end of the insertion tube abuts against the one-way sealing plate, forcing the one-way sealing plate to bend and deform, thereby connecting the flow tube and the insertion tube. The cleaning fluid in the storage box flows into the flow channel through the flow tube and the insertion tube in sequence, and after being soaked in the sponge strip through the outlet hole, when the scraper slides in the opposite direction, the sponge strip soaked in cleaning fluid cleans the baffle, thereby improving the cleaning effect on the upper surface of the baffle. After the insertion tube is removed from the flow tube, the one-way sealing plate elastically resets. Attached Figure Description

[0040] The following is in conjunction with the appendix Figures 1-13 This application will be described in further detail.

[0041] Example 1: This application discloses a forklift overhead guard, referring to... Figure 1 , Figure 2 The system includes a roof 1 and multiple support columns 2 connected to the roof 1. Specifically, the roof 1 includes a pair of parallel longitudinal beams 11 and several crossbeams 12 fixedly connected to the inner sidewalls of the two longitudinal beams 11. In this embodiment, three crossbeams 12 are provided. Four support columns 2 are provided and are respectively fixedly connected to the two ends of the two longitudinal beams 11. The lower part of the support columns 2 is used to fix them to the body of the forklift.

[0042] A baffle 3 is movably connected between two adjacent crossbeams 12. The baffle 3 is a transparent plate; in this embodiment, the baffle 3 is made of glass. Multiple baffles 3 are provided and spaced apart along the length of the crossbeam 12. A rotating shaft 31 is fixedly attached to the side wall of the crossbeam 12 near the end face of the baffle 3. The axis of the rotating shaft 31 is parallel to the length of the longitudinal beam 11, and the end face of the baffle 3 abuts against the inner side wall of the crossbeam 12. The crossbeam 12 is provided with a conversion mechanism 5 that drives multiple rotating shafts 31 to rotate synchronously to realize the rotation of the baffles 3. Under normal conditions, multiple baffles 3 are in a vertical state, and a large ventilation space is formed between two adjacent baffles 3. By driving multiple rotating shafts 31 to rotate 90° through the conversion mechanism 5, the baffles 3 are switched to a horizontal state. The sides of two adjacent baffles 3 are pressed against each other, thereby sealing the ventilation space. The baffle 3 located at the outermost edge has a gap between it and the inner side wall of the longitudinal beam 11 in the horizontal state to form a drainage channel.

[0043] Reference Figure 3 , Figure 4Furthermore, the side wall of the baffle 3 is provided with a mounting groove 32, and a sealing strip 4 is provided on the side of the baffle 3. The sealing strip 4 is a rubber strip, and a mounting clip 41 that is embedded and fixed in the mounting groove 32 is provided on one side of the sealing strip 4. When the baffle 3 is in a horizontal state, in the two sealing strips 4 that abut against each other, the outer side wall of one sealing strip 4 is provided with a sealing groove 42, and the outer side wall of the other sealing strip 4 is provided with a sealing clip 43 that is engaged in the sealing groove 42, thereby increasing the contact area between the two sealing strips 4 and improving the sealing performance between the two sealing strips 4.

[0044] Reference Figure 5 The crossbeam 12 located at the edge has a mounting cavity 121, and the end of the rotating shaft 31 extends into the mounting cavity 121. The conversion mechanism 5 includes a transmission wheel 51, a synchronous belt 52, and a first driving member. The transmission wheel 51 is built into the mounting cavity 121 and coaxially fixedly sleeved on the rotating shaft 31. The synchronous belt 52 is wound between two adjacent transmission wheels 51. The first driving member is a first motor 53 fixedly connected to the outer wall of the crossbeam 12. The first motor 53 is a stepper motor, and the output shaft of the first motor 53 is coaxially fixedly connected to one of the rotating shafts 31.

[0045] Reference Figure 2 , Figure 6 One of the longitudinal beams 11 has a storage groove 111 on its inner sidewall, which extends to the upper end face of the longitudinal beam 11. The storage groove 111 is located between two adjacent crossbeams 12 and is above the rotating shaft 31. A scraper 6, normally built into the storage groove 111, is slidably connected between the two adjacent crossbeams 12. A scraper strip 61 for abutting against the upper end face of the baffle 3 is fixedly connected to the lower end face of the scraper 6. The scraper strip 61 is elastically set. In this embodiment, the scraper strip 61 is a sponge strip.

[0046] Reference Figure 6 , Figure 7 The scraper 6 has a liquid flow channel 63. The lower end face of the scraper 6 is provided with an outlet hole 65 that communicates with the liquid flow channel 63. The sponge strip covers the outlet hole 65. The side of the scraper 6 away from the storage tank 111 is fixedly connected to an insertion tube 64 that communicates with the liquid flow channel 63.

[0047] Reference Figure 7 , Figure 8 , Figure 9A liquid storage box 8, containing cleaning fluid, is fixedly connected to the upper end face of another longitudinal beam 11. A flow pipe 81, which passes through the longitudinal beam 11 and extends out of its inner sidewall, is fixedly connected to the bottom wall of the liquid storage box 8. The flow pipe 81 is equipped with multiple one-way sealing plates 82 that normally close its opening. These one-way sealing plates 82 are distributed circumferentially around the flow pipe 81 and are elastically arranged. When the insertion tube 64 is slidably inserted into the flow pipe 81, the end of the insertion tube 64 abuts against the one-way sealing plate 82, forcing the one-way sealing plate 82 to bend and deform, thereby connecting the flow pipe 81 and the insertion tube 64.

[0048] Reference Figure 5 , Figure 6 , Figure 10 The inner sidewall of the crossbeam 12 has an upper sliding groove 122 above the rotating shaft 31 and a lower sliding groove 123 below the rotating shaft 31. The upper sliding groove 122 is connected to the receiving groove 111. Both sides of the scraper 6 have protruding sliders 62 that are slidably connected to the upper sliding groove 122. The longitudinal beam 11 is provided with a drive mechanism 7 that drives the sliders 62 to slide back and forth in the upper sliding groove 122. The drive mechanism 7 includes a pair of rollers 71 that are rotatably connected to the outer sidewalls of the two longitudinal beams 11, a transmission belt 72 that passes through the longitudinal beam 11 and wraps around the rollers 71, and a second drive member that drives the rollers 71 to rotate. The two ends of the transmission belt 72 are fixedly connected to the two sidewalls of the slider 62, the upper layer of the transmission belt 72 is built into the upper sliding groove 122, and the lower layer of the transmission belt 72 is built into the lower sliding groove 123. The second driving component is a second motor 73 fixedly connected to the outer wall of the longitudinal beam 11, and the output shaft of the second motor 73 is coaxially fixedly connected to the roller 71.

[0049] The implementation principle of a forklift overhead guard in this application embodiment is as follows: Under normal conditions, multiple baffles 3 are in a vertical state, and a large ventilation space is formed between two adjacent baffles 3, increasing the ventilation of the cab. When encountering rain during outdoor operations, the conversion mechanism 5 drives multiple rotating shafts 31 to rotate 90°, thereby switching the baffles 3 to a horizontal state. The sides of two adjacent baffles 3 abut against each other, thereby sealing the ventilation space and effectively reducing the possibility of rainwater falling into the cab.

[0050] Furthermore, the drive mechanism 7 drives the scraper 6 to reciprocate sliding motion. On the one hand, it pushes the rainwater on the baffle 3 toward the edge of the roof 1, accelerating the rainwater discharge speed. On the other hand, it can scrape and clean the rainwater or dust and other debris adhering to the baffle 3, improving the cleanliness of the upper surface of the baffle 3 and providing good visibility, making it easier for the driver in the cab to observe the working conditions above the forklift through the baffle 3.

[0051] During the cleaning operation of the scraper 6 on the upper surface of the baffle 3, the scraper 6 slides towards the longitudinal beam 11 containing the liquid storage box 8, and when the insertion tube 64 slides into the flow pipe 81, the end of the insertion tube 64 abuts against the one-way sealing plate 82, forcing the one-way sealing plate 82 to bend and deform, thereby connecting the flow pipe 81 and the insertion tube 64. The cleaning liquid in the liquid storage box 8 flows into the flow channel 63 through the flow pipe 81 and the insertion tube 64 in sequence, and after being soaked in the sponge strip through the outlet hole 65, when the scraper 6 slides in the opposite direction, the sponge strip soaked in cleaning liquid cleans the baffle 3, thereby improving the cleaning effect on the upper surface of the baffle 3. After the insertion tube 64 is removed from the flow pipe 81, the one-way sealing plate 82 elastically resets and seals the opening of the flow pipe 81, effectively reducing the possibility of the cleaning liquid in the liquid storage box 8 leaking out from the flow pipe 81 and reducing the waste of cleaning liquid.

[0052] Example 2: The difference between this embodiment and Embodiment 1 is that, referring to... Figure 11 , Figure 12 , Figure 13 The liquid flow tube 81 includes a vertical tube 811 fixedly installed through the bottom wall of the liquid storage box 8 and through the longitudinal beam 11, and a horizontal tube 812 fixedly connected to the lower end of the vertical tube 811 and extending through the inner side wall of the longitudinal beam 11. The upper end of the vertical tube 811 extends into the liquid storage box 8, and a one-way sealing piece 82 is provided at the opening of the horizontal tube 812.

[0053] A movable piece 83 is vertically slidably connected to the inner wall of the liquid storage box 8. A movable sleeve 84, which is slidably inserted into the vertical tube 811, is fixedly connected to the movable piece 83. The upper end of the movable sleeve 84 is closed, and the lower end is open to communicate with the inner cavity of the vertical tube 811. A first through hole 813 is formed on the upper outer peripheral wall of the vertical tube 811, and a second through hole 841, corresponding to the position of the first through hole 813, is formed on the outer peripheral wall of the movable sleeve 84. An elastic element, a spring 85, is provided between the movable piece 83 and the bottom wall of the liquid storage box 8. One end of the spring 85 is fixedly connected to the lower end face of the movable piece 83, and the other end is fixedly connected to the bottom wall of the liquid storage box 8. When the lower end face of the movable piece 83 abuts against the upper end face of the vertical tube 811, the first through hole 813 and the second through hole 841 communicate. A rope hole is provided on the upper part of the outer side wall of the liquid storage box 8. A connecting rope 33 is fixedly connected to the side of the baffle 3 closest to the liquid storage box 8. The other end of the connecting rope 33 passes around the lower end face of the longitudinal beam 11 and the outer side wall of the longitudinal beam 11, passes upward through the rope hole, and extends downward to be fixedly connected to the upper end face of the movable piece 83.

[0054] The implementation principle of Example 2 is as follows: Under normal conditions, the baffle 3 is in a vertical position. The baffle 3 pulls the movable piece 83 upward through the connecting rope 33, thereby causing the movable sleeve 84 to move upward. At this time, the spring 85 undergoes elastic deformation and has elastic potential energy, causing the first through hole 813 and the second through hole 841 to be misaligned. This causes the outer peripheral wall of the movable sleeve 84 to block the first through hole 813, and the outer peripheral wall of the vertical pipe 811 to block the second through hole 841, thus preventing the cleaning liquid in the liquid storage box 8 from flowing in. Liquid pipe 81; When the baffle 3 is switched to the horizontal state, the end of the baffle 3 with the connecting rope 33 fixed to it rotates towards the longitudinal beam 11, the connecting rope 33 is in a relaxed state, the spring 85 forces the movable piece 83 to move down and reset, so that the lower end face of the movable piece 83 abuts against the upper end face of the vertical pipe 811, the first through hole 813 and the second through hole 841 are connected, and the cleaning liquid in the liquid storage box 8 flows into the liquid pipe 81 in sequence through the first through hole 813 and the second through hole 841, which facilitates subsequent cleaning operations.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
