Description

Technical Field

[0001] The present application relates to the technical field of trolleys, and in particular to a trolley and a base-integrated mobile unit using the trolley. Background Art

[0002] A trolley is a handling vehicle used for pushing and pulling, and trolleys for different purposes have different body structures.

[0003] In the related art, a trolley includes a frame, a deck, and rollers. The frame is formed by bending steel pipes; the deck is disposed inside the frame, and the periphery of the deck is welded to the inner side of the frame; the rollers are disposed on the frame for the trolley to move. When the trolley is in use, the load is installed on the top surface of the deck, and the load is pushed to a designated position for use through the rollers.

[0004] Regarding the above related art, the inventor believes that since the frame is made of steel pipes, and the wall thickness of the steel pipes is relatively thin and the wall area is relatively small, the welding area between the steel pipes and the deck is relatively small. When the trolley moves quickly and works normally, the rigidity between the steel pipes and the deck is weak, resulting in an enhanced vibration of the trolley. After long-term use of the trolley, it is prone to rupture due to long-term severe vibration, and the service life of the trolley needs to be improved. Therefore, the present application provides a trolley and a base-integrated mobile unit using the trolley. Summary of the Utility Model

[0005] In order to improve the problem that the trolley is prone to rupture due to long-term severe vibration after long-term use and to increase the service life of the trolley, the present application provides a trolley and a base-integrated mobile unit using the trolley.

[0006] In a first aspect, a trolley provided by the present application adopts the following technical solution:

[0007] A trolley includes a frame, a deck, and rollers. The deck and the rollers are both disposed on the frame. The frame includes a support frame body, which is formed by sequentially connecting plates. The side edges in the width direction of the plates are bent. The deck is disposed inside the support frame body, and both ends of the deck are fixedly connected to the side walls of the plates.

[0008] By adopting the above technical solution, when the trolley is installed, both ends of the deck are fixedly connected to the side walls of the plates. The side walls of the plates have a relatively large area, so that the connection area between the deck and the main support surface of the plates is larger, thereby increasing the connection strength between the plates and the deck, making the support stable and not easily damaged. When the trolley moves quickly and works normally, the rigidity between the steel pipes and the deck is enhanced, the vibration of the trolley is weakened, and the trolley is not easily ruptured. The bending of the side edges in the width direction of the plates helps to improve the structural strength of the plates themselves, ultimately playing a role in increasing the service life of the trolley.

[0009] Optionally, axle shafts penetrate through both sides of the support frame body, and the rollers are installed at both ends of the axle shafts.

[0010] By adopting the above technical solution, when using a steel pipe as the frame, the axle shafts are often installed by welding axle shaft brackets at the bottom of the frame. However, the axle shaft brackets are prone to damage due to welding quality problems.

[0011] With the arrangement in this application, the axle shafts are directly installed through the support frame body, which is stable and reliable, convenient for disassembly and installation, and not easily deformed or damaged due to the movement of the trolley and working vibration.

[0012] Optionally, the rollers are arranged on both sides at one end of the support frame body. A hand-held part is arranged at the end of the support frame body far from the rollers, and a support frame body is arranged at the bottom of the support frame body.

[0013] By adopting the above technical solution, when the trolley needs to be moved, the operator holds the hand-held part or hooks the hand-held part with a vehicle tool to lift one end of the trolley upward to realize the movement of the trolley. Since the hand-held part and the rollers are located at both ends of the support frame body in this application, a relatively long lever is formed, and loads of more than 200 kg can be easily moved manually or after hooking a vehicle tool.

[0014] When the trolley is moved to the designated position, put down the lifted end of the hand-held part. The support frame body supports the whole trolley and maintains the balance at both ends of the support frame body. At this time, the load installed on the ship board can be used normally.

[0015] Optionally, the support frame body includes a front support and a rear support. The front support is arranged at the end of the support frame body close to the hand-held part, and the rear support is arranged at the end of the support frame body close to the rollers. The bottoms of the front support and the rear support are lower than the bottoms of the rollers.

[0016] By adopting the above technical solution, the front support and the rear support are provided at the bottom of the trolley. When the load on the ship board is used normally, it is supported by the front support and the rear support. The load can work stably and more reliably, and at the same time, it helps to ensure the service life and supporting cost of the rollers.

[0017] When the trolley is moved, it can be set according to the actual situation. Lift the hand-held part to tilt the load by more than 20°, so that the rollers can contact the ground and switch the support of the support frame body to the movement of the rollers, which is convenient to operate.

[0018] Optionally, the hand-held part includes a mounting rod and a handle. The mounting rod is fixedly arranged on both sides of the top surface of the support frame body. A mounting through groove is formed on the side surface of the mounting rod far from the rollers. The end of the handle passes through the mounting through groove and is hinged in the mounting through groove.

[0019] By adopting the above technical solution, it is convenient for the operator to adjust the use angle of the handle according to the actual situation, which helps to improve the convenience and comfort.

[0020] Optionally, a lifting frame is detachably arranged on the top surface of the support frame body.

[0021] Optionally, a lifting hole is formed on the side surface of the support frame body.

[0022] By adopting the above technical solution, the lifting frame is detachably arranged and has multiple lifting schemes. The lifting method can be selected according to the actual needs, and whether to configure the lifting frame can also be selected. The cart can be packaged and transported by lifting, or the lifting frame can be disassembled, which helps to improve the practicality of the cart.

[0023] Optionally, a shock pad is fixedly arranged on the top surface of the deck, and the load used in cooperation with the cart is mounted on the shock pad.

[0024] By adopting the above technical solution, the shock pad can play a shock-absorbing role and reduce the vibration generated between the load and the deck, which helps to improve the service life of the cart and the load.

[0025] Optionally, the frame further includes a lifting member. The lifting member is arranged in the support frame body and fixedly connected to the bottom inside the support frame body. The deck is connected to the top inside the support frame body, and a built-in space is formed by the interval between the lifting member and the deck.

[0026] By adopting the above technical solution, the required supplies can be stored in the built-in space, improving the convenience.

[0027] In the second aspect, a base-integrated mobile unit provided by the present application adopts the following technical solution:

[0028] A base-integrated mobile unit includes the above cart. A fuel tank is arranged in the built-in space. A limiting notch is provided at the top of the fuel tank, and the limiting notch penetrates through both sides in the width direction of the fuel tank. The wheel axle passes through the limiting notch;

[0029] The load used in cooperation with the cart is mounted on the deck. The load is a fuel-consuming component and is supplied with fuel by the fuel tank.

[0030] By adopting the above technical solution, since when the load needs to use the fuel tank as a driving raw material, the fuel tank is usually placed on the top of the load for installation. The fuel tank is usually the fuel tank of a generator or other products, with a small capacity and unable to support the long-term operation of high-power loads. If a large-capacity finished fuel tank is used, the overall height of the equipment will be too high, it will be unsightly, the transportation cost will increase, and it is not easy to set up a fuel tank support to support the weight of the fuel tank.

[0031] With the fuel tank arrangement in this application, the fuel tank can be installed in the built-in space. The provision of the limiting notch can make way for the axle, facilitating the installation of the axle; the axle can then limit the fuel tank through the limiting notch, improving the stability of the fuel tank installation. The fuel tank is integrated inside the frame, enabling a larger fuel tank volume to be set. When the load is a high-power device, it is beneficial for the high-power device to operate continuously for a long time. One only needs to adjust the size of the fuel tank according to the required continuous operating time, facilitating the selection of the fuel tank.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. This application uses the support frame as the main support component for the load, and the side edges in the width direction of the plate of the support frame are bent, having good structural strength. The connection area between the ship plate and the main support surface of the plate is large, and the support is stable and not easily damaged. Inside this support frame and integrated with the inner side of the support frame are a fuel tank, a lifting rack, a handle, rollers, a support frame body, and a shock pad, which is applicable to a movable base for various loads;

[0034] 2. The fuel tank is integrated inside the frame, enabling a larger fuel tank volume to be set. When the load is a high-power device, it is beneficial for the high-power device to operate continuously for a long time. One only needs to adjust the size of the fuel tank according to the required continuous operating time, facilitating the selection of the fuel tank.

[0035] 3. Through the provision of the support frame body, when the load on the ship plate is in normal use, it is supported by the front support and the rear support. The load can operate stably and more reliably, and at the same time, it helps to ensure the service life and supporting cost of the rollers; when the cart is moving, lift the handheld part to tilt the load, so that the rollers can contact the ground, and switch the support of the support frame body to the movement of the rollers, which is convenient to operate.

[0036] 4. The lever design in this application is relatively long, and it is easy to lift and move a load with a relatively large mass by manpower or move it after hanging a vehicle tool. The mass of the load can be up to 200 kg.

[0037] 5. The lifting rack is detachably arranged and has multiple lifting schemes. One can choose the lifting method according to actual needs and choose whether to configure the lifting rack. It can not only realize the packaging and transportation of the cart through lifting, but also disassemble the lifting rack, which helps to improve the practicability of the cart.

Detailed implementation manners

[0046] The following will further describe the present application in detail with reference to the Figure 1-7 accompanying drawings.

[0047] The embodiment of the present application discloses a trolley and a base integrated mobile unit using the trolley.

[0048] In a first aspect, the embodiment of the present application discloses a trolley. Referring to Figure 1 and Figure 2 , the trolley includes a frame 1 and a ship plate 2, a roller 3, a handheld part 4, a lifting frame 5 and a support frame body 6 mounted on the frame 1. In the embodiment of the present application, the load used in cooperation with the trolley is a diesel-powered water pump 7, and the load can also be a gasoline-powered water pump, an electric water pump and other equipment, which can be selected and installed according to actual situations. The diesel-powered water pump 7 is installed on the ship plate 2, the roller 3 and the handheld part 4 are respectively close to both ends of the frame 1, and the lifting frame 5 is installed above the frame 1 for lifting the whole trolley.

[0049] When the trolley is in use, one end of the trolley is lifted upward through the handheld part 4 to realize the movement of the trolley. Since the handheld part 4 and the roller 3 in this application are respectively located at both ends of the support frame 11, there is a relatively long lever, and loads of more than 200 kg can be easily moved by manpower or after hooking up a vehicle; when the trolley moves to the designated position, the lifted end of the handheld part 4 is put down. At this time, the diesel-powered water pump 7 installed on the ship board 2 is in normal use.

[0050] Referring to Figure 2 , Figure 3 and Figure 4 , two ship boards 2 with different widths are arranged in parallel. The frame 1 includes a support frame 11 and a lifting member 12. The support frame 6 supports the whole trolley and maintains the balance at both ends of the support frame 11. The support frame 11 is formed by sequentially connecting plates 13 with bolts and is rectangular in shape. The side edges in the width direction of the plate 13 are bent outward. In the embodiment of this application, the plate 13 is a channel steel made by sheet metal bending. The ship board 2 is installed in the support frame 11, and both ends of the ship board 2 are welded to the side walls of the two side plates 13 respectively.

[0051] When the trolley is installed, both ends of the ship board 2 are welded to the side walls of the plates 13. The side walls of the plates 13 have a relatively large area, so that the connection area between the ship board 2 and the main support surface of the plates 13 is larger, thereby improving the connection strength between the plates 13 and the ship board 2, making the support stable and not easily damaged. When the trolley moves quickly and works normally, the rigidity between the steel pipe and the ship board 2 is enhanced, the vibration of the trolley is reduced, and the trolley is not easily broken. Since the plate 13 is a channel steel, it helps to improve the structural strength of the plate 13 itself, and finally plays a role in increasing the service life of the trolley.

[0052] Referring to Figure 1 and Figure 3 , six shock pads 21 are arrayed on the top surface of the ship board 2. The bottom of the diesel-powered water pump 7 is fixedly connected to the ship board 2 through bolts passing through the shock pads 21. The shock pads 21 can play a shock-absorbing role, reduce the vibration generated between the diesel-powered water pump 7 and the ship board 2, and help to increase the service life of the trolley and the diesel-powered water pump 7.

[0053] Referring to Figure 1 , Figure 2 and Figure 5, the handheld part 4 includes a mounting rod 41 and a handle 42. The mounting rod 41 is vertically arranged, and the bottom of the mounting rod 41 is fixedly connected to both sides of the top surface of the support frame 11 by bolts. The two mounting rods 41 on both sides are fixedly connected by a connecting rod 43 to play a strengthening role. An installation through groove 411 is formed on the side of the mounting rod 41 away from the roller 3. The end of the handle 42 passes through the installation through groove 411 and is hinged in the installation through groove 411 by a rotating rod 412, which facilitates the operator to adjust the use angle of the handle 42 according to the actual situation and helps improve convenience and comfort.

[0054] Referring to Figure 2 and Figure 3 , lifting holes 111 are formed at both ends of the side of the support frame 11 close to the handheld part 4. The diesel-powered water pump 7 is located inside the lifting frame 5, and the lifting frame 5 is detachably connected to the top surface of the support frame 11 by bolts. This application has multiple lifting schemes, and the lifting method can be selected according to actual needs, as well as whether to configure the lifting frame 5. It can not only realize the packaging and transportation of the trolley through lifting, but also disassemble the lifting frame 5, which helps improve the practicality of the trolley.

[0055] Referring to Figure 2 and Figure 4 , the support frame body 6 includes a front support 61 and a rear support 62 arranged in a "V" shape. There are two front supports 61 and two rear supports 62, and they are all fixedly connected to the bottom surface of the support frame 11 by bolts. The front support 61 is arranged at one end of the support frame 11 close to the handheld part 4, and the rear support 62 is arranged at one end of the support frame 11 close to the roller 3. The bottoms of the front support 61 and the rear support 62 are slightly lower than the bottom of the roller 3. In the embodiment of this application, the bottoms of the front support 61 and the rear support 62 are 2 mm lower than the bottom of the roller 3.

[0056] The front support 61 and the rear support 62 are provided at the bottom of the trolley. When the diesel-powered water pump 7 is in normal use, it is supported by the front support 61 and the rear support 62, and the load can work stably and more reliably. At the same time, it helps ensure the service life and supporting cost of the roller 3; when the trolley moves, lift the handheld part 4 to tilt the load by more than 20°, so that the roller 3 can contact the ground, and switch the support of the support frame body 6 to the movement of the roller 3, which is convenient to operate.

[0057] Referring to Figure 4 , Figure 6 and Figure 7, a wheel axle 31 penetrates through both sides of the support frame 11, and the rollers 3 are fixedly connected to both ends of the wheel axle 31 by bolts. When using a steel pipe as the frame 1, it is common to install the wheel axle 31 by welding a wheel axle 31 support at the bottom of the frame 1. However, the wheel axle 31 support is easily damaged due to welding quality problems. Through the setting in this application, the wheel axle 31 is directly installed through the support frame 11, which is stable and reliable, convenient for disassembly and installation, and is not easily deformed or damaged due to the movement of the trolley and working vibration.

[0058] Referring to Figure 3 and Figure 4 , the lifting member 12 is two spaced lifting rods, which are arranged inside the support frame 11 and welded to the bottom inside the support frame 11. The ship plate 2 is welded to the top inside the support frame 11. The lifting rods and the ship plate 2 are spaced to form an internal space 8 for storing required supplies, improving convenience.

[0059] The implementation principle of a trolley in an embodiment of this application is as follows: When installing the trolley, first assemble the plates 13 inside the support frame 11 and on the inner side of the support frame 11, and then fasten the front support 61 and the rear support 62 to the support frame 11 by bolts. Subsequently, weld both ends of the lifting rod to the bottom of the side of the plate 13. Place the fuel tank 81 on the lifting rod, and weld and install the ship plate 2 to install the fuel tank 81 inside the internal space 8. Then pass the wheel axle 31 through both sides of the support frame 11, and fixedly connect the rollers 3 to both ends of the wheel axle 31 by bolts. Then fix the mounting rod 41 to the top surface of the support frame 11 by bolts, pass the end of the handle 42 through the mounting slot 411 and hinge it inside the mounting slot 411 through the rotating rod 412 to realize the installation of the handheld part 4. Finally, fix the bottom of the diesel-powered water pump 7 to the ship plate 2 by bolts passing through the shock pad 21, and disassemble and assemble the lifting frame 5 according to the actual situation to complete the installation of the entire trolley.

[0060] When the trolley is placed flat, it is supported by the front support 61 and the rear support 62. At this time, the diesel-powered water pump 7 can be used normally, and it can work stably and more reliably. At the same time, it helps to ensure the service life and supporting cost of the rollers 3. When the trolley is moving, lift the handheld part 4 to tilt the load by more than 20°, so that the rollers 3 can contact the ground, and switch the support of the support frame 6 to the movement of the rollers 3, which is convenient to operate.

[0061] In the second aspect, an embodiment of this application discloses a base-integrated mobile unit. Referring to Figure 1-3 , Figure 6 and Figure 7, the base-integrated mobile unit includes the above-mentioned trolley. Additionally, a fuel tank 81 is stored in the built-in space 8. A rectangular limiting notch 82 is provided at the top of the fuel tank 81, and the limiting notch 82 penetrates both sides in the width direction of the fuel tank 81. The axle 31 passes through the limiting notch 82. Since when using the fuel tank 81 as a driving raw material for carrying goods, the fuel tank 81 is usually placed on top of the goods for installation. And the fuel tank 81 is usually the fuel tank of a generator or other products, with a small capacity and unable to support the long-term operation of high-power goods. If a large-capacity finished fuel tank 81 is used, it will cause the overall height of the equipment to be too high, not aesthetically pleasing, increase transportation costs, and it is not easy to set up a fuel tank 81 support to support the weight of the fuel tank 81.

[0062] Through the setting of the fuel tank 81 in this application, the fuel tank 81 can be installed in the built-in space 8 to provide driving raw materials for the diesel-powered water pump 7. The setting of the limiting notch 82 can make way for the axle 31, facilitating the installation of the axle 31; the axle 31 can then limit the fuel tank 81 through the limiting notch 82, improving the stability of the fuel tank 81 installation. The fuel tank 81 is integrated inside the frame 1, and a larger fuel tank 81 volume can be set. When the carried goods are high-power equipment, it is beneficial for the high-power equipment to work continuously for a long time. It only needs to adjust the size of the fuel tank 81 according to the required continuous working time, which is convenient for fuel tank 81 selection. This application uses sheet metal folded into channel steel as the main supporting component of the trolley, and a lifting frame 5, a handle 42, rollers 3, a support frame body 6 and a shock pad 21 are provided on this supporting component, and the fuel tank 81 is integrated, which is applicable to a movable base for various carried goods.

[0063] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
