Description

Technical Field

[0001] The present application relates to the technical field of base equipment, and in particular to a mobile base device. Background Art

[0002] With the development of science and technology, we have some understanding of radiation and can control it. The main sources of radiation today are man-made products and radioactive substances in nature. Because radiation can cause great damage to the human body, we need to use detection equipment to detect our living environment. Because the detection equipment needs to be moved to change its working environment, there are certain requirements for the structures such as the bottom rollers and bottom plate supports of the detection equipment.

[0003] Nowadays, most of the testing equipment that needs to be moved are equipped with a load-bearing chassis underneath. The load-bearing chassis is mostly a movable base composed of a single base plate and rollers. The testing equipment required for installation work is configured on the base plate. When the testing equipment is docked for operation, it is necessary to adjust the position up and down or move forward and backward on the base plate. Because there is no other mechanism to assist in supporting it, when the testing equipment moves on the base plate, the whole body will shake, making the base unstable. Utility Model Content

[0004] In order to improve the convenience, stability and reliability of the mobile base staying, the present application provides a mobile base device.

[0005] The present application provides a mobile base device, which adopts the following technical solution:

[0006] A mobile base device comprises a frame, casters are arranged at the bottom of the frame, a loading platform is arranged on the frame, a supporting component is arranged on the loading platform, and a locking mechanism for positioning the supporting component is arranged on the loading platform.

[0007] By adopting the above technical solution, the casters can flexibly change the movement direction of the base. When the base reaches the specified position, the locking mechanism is used to unlock the support component and quickly open the support component on the loading platform. After the support component is opened, the locking mechanism is used to fix and lock the support component again. The support component strengthens the fixed support of the base to ensure that the equipment is stable and stable during use. When the base needs to change the working position, the locking mechanism unlocks the support component and withdraws the support component to the side of the frame to facilitate the base to change the working position.

[0008] In a specific possible implementation scheme, the supporting component includes a connecting plate, one end of the connecting plate is connected to the loading platform, a support rod is provided at one end of the connecting plate away from the loading platform, a support block is provided at the lower end of the support rod, and a handle is provided at the upper end of the support rod.

[0009] By adopting the above technical solution, one end of the connecting plate is connected to the loading platform, and the other end is equipped with a support rod and a support block. When the support component is not needed, the support component can be folded on the frame. If the support component is needed, the connecting plate can be quickly opened and the support rod can be quickly adjusted using the handle control. The support block increases the contact area with the ground, strengthens the fixed support of the base, and makes the base stop more stably and reliably.

[0010] In a specific possible implementation scheme, a limit block is provided at the upper end of the support rod, the limit block is polygonal, a polygonal groove is provided on the handle, and the limit block is inserted into the polygonal groove and installed in cooperation with the handle.

[0011] By adopting the above technical solution, a limit block is set at the upper end of the support rod, and the handle is a single accessory that can be flexibly installed and removed from the support frame. When installed and used, it is easy to control the rotation of the support rod. After use, the handle is taken off to facilitate the folding and docking of the support component on the frame. At the same time, one handle can be disassembled and used for multiple support rods, reducing the number of installed handles, which is beneficial to reducing the overall weight of the frame and facilitating the movement of the base, thereby improving work efficiency.

[0012] In a specific feasible implementation scheme, the locking mechanism includes a button, which is slidably mounted on the loading platform, and a cavity is opened in the loading platform, and a first support frame is mounted on the loading platform in the cavity, and a first push rod is mounted on the first support frame, the first push rod is connected to the lower end of the button, and the other end of the first push rod is connected to a first locking block, and the first locking block is arranged in the cavity and is slidably connected to the loading platform; a second support frame is arranged at the inner bottom of the loading platform, and a second push rod is mounted on the second support frame, the second push rod is connected to the lower end of the button, and the other end of the second push rod is connected to the second locking block, and the second locking block is arranged in the cavity and is slidably connected to the loading platform.

[0013] By adopting the above technical solution, when the button is pressed, the first locking block and the second locking block can be moved up at the same time to unlock the support component, so that the support component can rotate freely on the loading platform. When the button is released, the support component can be quickly fixed and locked, and the locking method is pin locking with strong locking ability, so that the support component can stably support the base.

[0014] In a specific feasible implementation scheme, the first push rod includes a first straight rod, the first straight rod is rotatably connected to the first support frame, a first U-shaped rod is installed at one end of the first straight rod close to the first locking block, the first straight rod and the first U-shaped rod are installed at an angle, and the first U-shaped rod is connected to the first locking block; the second push rod includes a second straight rod, the second straight rod is rotatably connected to the second support frame, a second U-shaped rod is installed at one end of the second straight rod close to the second locking block, the second straight rod and the second U-shaped rod are installed at an angle, and the second U-shaped rod is connected to the second locking block.

[0015] By adopting the above technical solution, the first U-shaped rod and the second U-shaped rod are connected to the first locking block and the second locking block respectively, and the first push rod and the second push rod respectively provide supporting force on both sides of the first locking block and the second locking block when unlocking the upward force of the first locking block and the second locking block. At the same time, the straight rod and the U-shaped rod are installed at a certain angle, which is beneficial for the push rod to support the locking block when rotating, thereby preventing the first locking block and the second locking block from being stuck due to uneven force directions.

[0016] In a specific feasible implementation scheme, the end of the first straight rod away from the first U-shaped rod is set to a spherical shape, the ports of the first U-shaped rod away from the first straight rod are all set to a spherical shape, the end of the second straight rod away from the second U-shaped rod is set to a spherical shape, and the ports of the second U-shaped rod away from the second straight rod are all set to a spherical shape.

[0017] By adopting the above technical solution, the spherical setting enables the first U-shaped rod and the second U-shaped rod to respectively contact the first locking block and the second locking block at the contact position to form point-surface contact, thereby reducing the friction force. At the same time, it can effectively prevent the first push rod and the second push rod from respectively driving the first locking block and the second locking block to rotate when they rotate, so that the first locking block and the second locking block move in the vertical direction.

[0018] In a specific embodiment, the casters include fixed casters and swivel casters.

[0019] By adopting the above technical solution, the universal caster can flexibly change the movement direction of the base, and the universal caster and the fixed caster are used in combination to facilitate the dragging of the base.

[0020] In a specific feasible implementation scheme, the loading platform includes a fixing rod, the lower end of the fixing rod is connected to a base plate, the side wall of the base plate close to the frame is connected to the side plate, the upper end of the fixing rod is connected to a top plate, the locking mechanism is arranged on the top plate, the side wall of the top plate close to the frame is connected to the side plate, a limiting plate is vertically arranged between the base plate and the top plate, the limiting plate is connected to the side plate close to the frame side wall, and the side plate is installed on the frame.

[0021] By adopting the above technical solution, the support component is connected to the fixed rod, which can make the support component more stable when rotating and opening. Adding a limit plate can effectively prevent the support component from rotating too small or too large, and can enable the support component to quickly rotate to the specified position and dock.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the setting of the supporting components, one end of the connecting plate is connected to the loading platform, and the other end is equipped with a supporting rod and a supporting block. When the supporting component is not needed, the supporting component can be folded on the frame. If the supporting component is needed, the connecting plate can be quickly opened and the supporting rod can be adjusted by the handle. The supporting block increases the contact area with the ground, and the base is fixed and supported again, so that the base can stop more stably and reliably.

[0024] 2. Through the setting of the locking mechanism, the locking mechanism is connected to the supporting component through the loading platform. The locking mechanism includes a button, a first locking block and a second locking block. By pressing and releasing the button, the supporting component can be quickly unlocked and fixedly locked, and the locking is firm and reliable, so that the supporting component can stably support the base.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] Example:

[0033] The present application embodiment discloses a mobile base device, referring to Figure 1 , including a frame 1, the frame 1 is welded by stainless steel plate and pipe, a push rod 2 is fixedly installed on the frame 1, and a caster 9 is arranged at the bottom of the frame 1. In this embodiment, the caster 9 includes a universal caster 4, which is rotatably installed on the bottom of the frame 1 near the push rod 2, and a brake mechanism 8 is arranged on the universal caster 4. A fixed caster 3 is rotatably installed on the bottom of the frame 1 away from the push rod 2. A plurality of loading platforms 5 are fixedly installed on the frame 1. In this embodiment, four loading platforms 5 are arranged, and two loading platforms 5 form a group, which are arranged on both sides of the frame 1 respectively. A supporting component 6 is rotatably installed on the loading platform 5, and a locking mechanism 7 for fixing and locking the supporting component 6 is arranged on the loading platform 5. The loading platform 5 is connected to the supporting component 6 through the locking mechanism 7.

[0034] When using the base, push the push rod 2 to change the direction of the base movement through the universal caster 4. When the base moves to the desired position, the brake mechanism 8 acts on the universal caster 4 to stop the base. The combination of the universal caster 4 and the brake mechanism 8 ensures that the base can be dragged flexibly and parking is convenient and reliable. After docking at the designated position, the support component 6 is quickly deployed to strengthen the positioning support, and the locking mechanism 7 quickly locks the support component 6 to ensure that the equipment on the base does not deflect or shake during use, thereby ensuring the accuracy and authenticity of data collection. In this embodiment, the brake mechanism 8 belongs to the prior art and is not described in detail in this application.

[0035] Reference Figure 1 and Figure 2The supporting component 6 includes a connecting plate 61, a first through hole 611 is provided at one end of the connecting plate 61, and the connecting plate 61 is rotatably connected to the loading platform 5 through the first through hole 611. A second through hole 612 is provided on the connecting plate 61 near the first through hole 611, and the locking mechanism 7 acts on the second through hole 612 to achieve a locking and unlocking state. The second through hole 612 is parallel to the first through hole 611 and both are vertically arranged. A third through hole 613 is provided at one end of the connecting plate 61 away from the first through hole 611, and the third through hole 613 is vertically arranged, and a thread is arranged in the third through hole 613. A supporting rod 62 is provided on the connecting plate 61, and the supporting rod 62 passes through the third through hole 613 and is threadedly connected to the connecting plate 61. A supporting block 63 is fixedly installed at the lower end of the supporting rod 62, and a limiting block is provided at the upper end of the supporting rod 62, and a handle 64 is installed on the limiting block. In this embodiment, the limiting block is polygonal, and a polygonal groove is provided on the handle 64. The limiting block is inserted into the polygonal groove and installed in coordination with the handle 64.

[0036] The connecting plate 61 is rotatably connected to the loading platform 5, and can be quickly unfolded to support the frame 1, and can also be quickly retracted to fit closely to the frame 1. The handle 64 is quickly installed on the support rod 62, and the handle 64 is rotated. The support rod 62 and the handle 64 are rotated together by the action of the limit block at the upper end of the support rod 62. The support rod 62 is adjusted in position by rising and falling through the thread, and a support block 63 is installed at the lower end of the support rod 62 to increase the contact area with the ground, making parking more stable.

[0037] Reference Figure 3 and Figure 4 The loading platform 5 includes a fixing rod 51, the lower end of the fixing rod 51 is connected to a bottom plate 52, the side wall of the bottom plate 52 close to the frame 1 is fixedly connected to the side plate 55, the upper end of the fixing rod 51 is connected to a top plate 53, the side wall of the top plate 53 close to the frame 1 is fixedly connected to the side plate 55, a locking mechanism 7 is provided on the top plate 53, the side plate 55 can be detachably mounted on the frame 1, a limiting plate 54 is vertically provided between the bottom plate 52 and the top plate 53, and the side wall of the limiting plate 54 close to the frame 1 is fixedly connected to the side plate 55.

[0038] When the support component 6 is needed, the connecting plate 61 can be rotated. Since the connecting plate 61 is rotatably installed on the fixing rod 51, the support component 6 can be easily and quickly expanded and collapsed. The connecting plate 61 is rotated to the limit plate 54. The limit plate 54 limits the maximum rotation angle of the connecting plate 61. This allows the connecting plate 61 to quickly determine and reach the specified position, which is beneficial to the rapid docking of the base.

[0039] Reference Figure 4A cavity 70 is provided on the loading platform 5, and the locking mechanism 7 includes a button 71, which is located above the cavity 70 and is slidably mounted on the loading platform 5.

A first locking block 75 and a second locking block 76 are slidably mounted on the loading platform 5, and the first locking block 75 and the second locking block 76 are respectively arranged below the button 71. When the connecting plate 61 is close to the frame 1, the first locking block 75 passes through the loading platform 5 and is slidably connected to the connecting plate 61. When the connecting plate 61 is opened, the second locking block 76 passes through the loading platform 5 and is slidably connected to the connecting plate 61. The first locking block 75 is fixedly connected to the second spring 77 on the side close to the button 71, and the second spring 77 is vertically arranged in the cavity 70. The other end of the second spring 77 is fixedly installed on the side wall of the loading platform 5 away from the first locking block 75. In this embodiment, when the second spring 77 is in a compressed state, the bottom end of the first locking block 75 just breaks away from the connecting plate 61. The second locking block 76 is fixedly connected to the third spring 78 on the side close to the button 71, and the third spring 78 is vertically arranged in the cavity 70. The other end of the third spring 78 is fixedly connected to the side wall of the loading platform 5 away from the second locking block 76. In this embodiment, when the third spring 78 is in a compressed state, the bottom end of the second locking block 76 just breaks away from the connecting plate 61. The first supporting frame 721 and the second supporting frame 722 are arranged in the cavity 70, and the first supporting frame 721 and the second supporting frame 722 are both fixedly installed on the loading platform 5. The first push rod 731 is rotatably mounted on the first support frame 721, one end of the first push rod 731 abuts against the lower end of the button 71, and the other end of the first push rod 731 abuts against the first locking block 75; the second push rod 732 is rotatably mounted on the second support frame 722, one end of the second push rod 732 abuts against the lower end of the button 71, and the other end of the second push rod 732 abuts against the second locking block 76.

[0040] Reference Figure 4 and Figure 5The first push rod 731 includes a first straight rod 7311, the first straight rod 7311 is rotatably connected to the first support frame 721, a first U-shaped rod 7312 is fixedly connected to the first straight rod 7311, the first straight rod 7311 and the first U-shaped rod 7312 are installed at an obtuse angle of 150°, the first U-shaped rod 7312 abuts against the first locking block 75, the end of the first straight rod 7311 away from the first U-shaped rod 7312 is set to a spherical shape, and the ports of the first U-shaped rod 7312 away from the first straight rod 7311 are all set to a spherical shape. The second top rod 732 includes a second straight rod 7321, which is rotatably connected to the second support frame 722, and a second U-shaped rod 7322 is fixedly connected to the second straight rod 7321. The second straight rod 7321 and the second U-shaped rod 7322 are installed at an obtuse angle of 150°, and the second U-shaped rod 7322 abuts against the second locking block 76. The end of the second straight rod 7321 away from the second U-shaped rod 7322 is set to a spherical shape, and the ports of the second U-shaped rod 7322 away from the second straight rod 7321 are all set to a spherical shape.

[0041] When the support component 6 is not in use, it can be folded and stay on the side of the frame 1, and the first locking block 75 in the locking mechanism 7 is inserted into the second through hole 612 to be fixed to a locked state. The second locking block 76 has no effect on the support component 6, which can prevent the support component 6 from hindering the movement of the base. When the base reaches the designated position to use the support component 6, the button 71 is pressed, and the button 71 causes the first push rod 731 and the second push rod 732 to rotate on the first support frame 721 and the second support frame 722 respectively, and the first push rod 731 and the second push rod 732 respectively drive the first locking block 75 and the second locking block 76 to move upward and stop when they are separated from the connecting plate 61, at which time the lower end of the first locking block 75 leaves the second through hole 612 and reaches the unlocked state, and when the connecting plate 61 reaches the limit plate 54, the button 71 is released, and the first locking block 75 and the second locking block 76 move downward respectively under the action of the second spring 77 and the third spring 78, at which time the first locking block 75 does not act on the support component 6, and the lower end of the second locking block 76 is inserted into the second through hole 612 on the connecting plate 61, and reaches the locked state again. By this method, the connecting plate 61 can be quickly unlocked and locked, and the locking method is firm and reliable, making the base more stable.

[0042] The implementation principle of the embodiment of the present application is as follows: when the working base needs to be moved, the base push rod 2 is pushed, and the base moving direction is adjusted through the universal caster 4 to drive the directional caster 3 to move at the same time. When the base moves to the specified position, the button 71 is pressed to unlock the support component 6, and the connecting plate 61 is rotated to reach the limit plate 54. The button 71 is released to fix and lock the support component 6 again. At this time, the handle 64 is rotated to adjust the support rod 62 to raise or lower the frame 1 to reach the use state. The frame 1 and the brake mechanism 8 adopt a frame structure and are welded with stainless steel plates and pipes. They have both certain strength and certain corrosion resistance. The bottom adopts high-quality high-load casters 9 to ensure that the base is dragged flexibly. After the base reaches the specified position, the support component 6 that can be quickly unlocked, unfolded and quickly withdrawn is used to strengthen the positioning support, so that the base stays more stably without shaking and deflection, thereby ensuring the normal use of the equipment on the base.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
