Description

Technical Field

[0001] The utility model relates to the technical field of equipment installation, in particular to a new type of equipment foot. Background Art

[0002] In some factory buildings, the floor's load-bearing capacity is limited due to various factors. Although the uniformly distributed load calculated based on the projected area of ​​the equipment does not exceed the floor's load-bearing capacity, the weight of each module varies, so the actual load applied to the floor by the equipment is not uniform. Furthermore, equipment installation requires leveling, a common practice for leveling equipment. This is achieved by using a spirit level and adjusting the height of the footings. From a geometric perspective, three points define a plane, so even after leveling, there's no guarantee that the force applied to each footing will conform to theoretical calculations or simulation analysis. In some cases, the area near the center of mass of the equipment is prone to local overload, causing changes in the equipment's state, impacting normal operation and machining accuracy, and even posing a serious threat to the safety of personnel, equipment, and the factory building.

[0003] In addition, the adjustment screw of the traditional foot is fixed to the foot plate with a screw. When the screw is tightened and the foot is under stress, the adjustment screw is rotated, and the adjustment screw forces the foot plate to rotate together. However, due to the large friction between the foot plate and the ground, it is very difficult to rotate the adjustment screw or even impossible to rotate, affecting the leveling of the equipment. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a new type of equipment foot.

[0005] The purpose of the utility model is achieved through the following technical solutions: A new type of equipment foot, including a force sensor, an adjustment screw and a foot plate;

[0006] The force sensor is used to connect the device;

[0007] The adjusting screw is arranged vertically, and the adjusting screw is threadedly connected to the force sensor;

[0008] The bottom end of the adjusting screw is rotatably connected to the foot plate.

[0009] The utility model connects the force sensor to the adjusting screw through a thread and directly connects the force sensor to the equipment, so that the load of the equipment is transmitted from the force sensor to the adjusting screw, and then to the foot plate and finally to the floor. By directly connecting the equipment to the force sensor, the load on the foot can be measured by the force sensor and the height of the force sensor (fixed to the equipment base) can be adjusted by rotating the adjusting screw, thereby adjusting the load on the foot, avoiding excessive load on the foot causing local overload on the floor, and thus avoiding affecting the equipment status.

[0010] In some embodiments, the footplate is provided with a bearing, and the adjusting screw is rotatably connected to the footplate via the bearing. Connecting the footplate and the adjusting screw via the bearing facilitates rotating the adjusting screw to adjust the height of the force sensor.

[0011] In some embodiments, the bearing comprises a thrust bearing. Since the adjusting screw is vertically arranged and mainly bears axial load, the thrust bearing provides good support for the adjusting screw and allows for smooth rotation, thereby adjusting the height of the force sensor.

[0012] In some embodiments, a first bearing seat is provided on the footplate, a second bearing seat is provided at the bottom end of the adjusting screw, the seat ring of the thrust bearing is provided in the first bearing seat, and the shaft ring of the thrust bearing is provided in the second bearing seat. The thrust bearing is limited by the first and second bearing seats.

[0013] In some embodiments, a retaining sleeve is provided on the first bearing seat, the retaining sleeve being threadedly connected to the outer surface of the first bearing seat. A limit plate is provided at the top of the retaining sleeve, which limits the second bearing seat within the retaining sleeve. The adjusting screw extends through the limit plate to the outside of the retaining sleeve. Due to the detachable structure of the thrust bearing, a retaining sleeve is provided, which is connected to the first bearing seat and encloses the second bearing seat within the retaining sleeve to prevent the adjustable screw from separating from the foot plate.

[0014] In some embodiments, the limit plate is provided with an opening through which the adjusting screw passes through the limit plate, and a step is provided at the bottom of the adjusting screw that mates with the opening. The opening allows the adjusting screw to pass through the fixing sleeve. Furthermore, the step at the bottom of the adjusting screw, with the circumferential surface of the step mating with the circumferential surface of the opening, prevents radial movement of the adjusting screw and improves the radial stability of the adjusting screw.

[0015] In some embodiments, a retaining nut is threadedly connected to the adjusting screw, and the retaining nut is configured to abut the bottom of the force sensor. The force sensor and adjusting screw are threadedly connected to prevent movement of the force sensor relative to the adjusting screw, which may cause vibration during device use. A retaining nut is provided to secure the force sensor.

[0016] In some embodiments, a locking nut is threadedly connected to the adjusting screw, and the locking nut is used to abut against the bottom of the fixing nut to prevent the fixing nut from loosening.

[0017] In some embodiments, the top of the adjusting screw is provided with a square head or a hexagonal head. By providing the square head or the hexagonal head on the top of the adjusting screw, it is convenient to twist the adjusting screw with a tool such as a wrench, so as to adjust the height of the force sensor.

[0018] In some embodiments, the thread on the adjusting screw is a fine pitch thread. Setting the thread of the adjusting screw as a fine pitch thread can make the adjustment more precise when adjusting the height of the force sensor, and improve the self-locking performance of the thread to prevent loosening.

[0019] The utility model has the following advantages:

[0020] The utility model can detect the load of the footing by connecting the force sensor to the equipment and then connecting the force sensor to the footing through an adjusting screw. The staff can rotate the adjusting screw according to the detected load to move the force sensor vertically along the screw to adjust the load applied by the equipment on the footing and avoid local overload of the floor. A thrust bearing is provided between the adjusting screw and the footplate, and the footplate and the adjusting screw can rotate to reduce the difficulty of adjustment.

[0026] like Figure 1 and Figure 2 As shown, a new type of equipment foot includes:

[0027] A force sensor 1, wherein the force sensor 1 is used for connecting a device;

[0028] An adjusting screw 2, wherein the adjusting screw 2 is vertically arranged and is threadedly connected to the force sensor 1;

[0029] The foot plate 3 is rotatably connected to the bottom end of the adjusting screw 2 .

[0030] Specifically, in this embodiment, the force sensor 1 is a spoke-type force sensor 1, wherein the large screw hole in the center of the force sensor 1 is threadedly connected to the adjustment screw 2, and several small screw holes on the edge of the force sensor 1 are connected to the device. The foot plate 3 in this embodiment is truncated.

[0031] During use, this embodiment connects the device to the force sensor 1, and the adjustment screw 2 is connected to the center screw hole of the force sensor 1. The top of the adjustment screw 2 protrudes from the force sensor 1 and extends through the device housing through a pre-set hole. The force sensor 1 transmits load data to the controller or host computer for staff to view. Based on the load data from the force sensor 1, the staff rotates the adjustment screw 2 to move the force sensor 1 up and down. As the force sensor 1 moves up and down, the load it experiences changes. By rotating the adjustment screw 2, the load on the footing is adjusted to a reasonable range, thereby avoiding the danger of local overload on the floor and ensuring the normal operation of the equipment.

[0032] Preferably, a bearing is provided on the footplate 3, and the adjusting screw 2 is rotatably connected to the footplate 3 via the bearing. After the foot is mounted on the equipment, the adjusting screw 2 is subjected to an axial load due to the weight of the equipment. Therefore, a bearing is provided to facilitate the rotation of the adjusting screw 2. In this embodiment, the bearing is provided at the center of the footplate 3.

[0033] Preferably, the bearing comprises a thrust bearing 4. Since the adjusting screw 2 is subjected to an axial load, ordinary deep groove ball bearings are not suitable for bearing the axial load. Therefore, the bearing is set as a thrust bearing 4, which can also work normally when subjected to a large axial load.

[0034] Preferably, a first bearing seat 31 is provided on the foot plate 3, a second bearing seat 21 is provided at the bottom end of the adjusting screw 2, the seat ring of the thrust bearing 4 is provided in the first bearing seat 31, and the shaft ring of the thrust bearing 4 is provided in the second bearing seat 21.

The adjusting screw 2 passes through the limit plate 51 to the outside of the fixing sleeve 5. Since the thrust bearing 4 is a separable bearing and is easily separated during use, a fixing sleeve 5 is provided. The fixing sleeve 5 is threadedly connected to the outer surface of the first bearing seat 31. A limit plate 51 is provided on the top of the fixing sleeve 5. The fixing sleeve 5 limits the second bearing seat 21 within the fixing sleeve 5 via the limit plate 51, preventing the first bearing seat 31 and the second bearing seat 21 from separating, that is, preventing the adjusting screw 2 from separating from the foot plate 3.

[0036] Preferably, the limiting plate 51 is provided with an opening 511 through which the adjusting screw 2 passes. The bottom of the adjusting screw 2 is provided with a step 22 that cooperates with the opening 511. The step 22 is provided at the bottom of the adjusting screw 2 and is located at the top of the second bearing seat 21. The circumferential surface of the opening 511 cooperates with the circumferential surface of the step 22 to define the radial position of the adjusting screw 2, thereby improving the radial stability of the adjusting screw 2.

[0037] Preferably, a fixing nut 6 is threadedly connected to the adjusting screw 2, and the fixing nut 6 is used to abut the bottom of the force sensor 1. Since vibration may occur during use of the device, to prevent relative movement between the force sensor 1 and the adjusting screw 2, the fixing nut 6 is provided on the adjusting screw 2, and the fixing nut 6 abuts the force sensor 1 to fix the force sensor 1.

[0038] Preferably, a lock nut 7 is threadedly connected to the adjusting screw 2, and the lock nut 7 is used to abut the bottom of the fixing nut 6. The lock nut 7 is provided on the adjusting screw 2 to prevent the fixing nut 6 from loosening, thereby preventing the force sensor 1 from moving.

[0039] Preferably, a square head or a hexagonal head is provided on the top of the adjusting screw 2. In this embodiment, a square head is provided on the top of the adjusting screw 2. In other embodiments, a hexagonal head can also be provided on the top of the adjusting screw 2. The square head makes it easier to use a tool such as a wrench to turn the adjusting screw 2 to adjust the height of the force sensor 1.

[0040] Preferably, the thread on the adjusting screw 2 is a fine thread. By setting the thread on the adjusting screw 2 as a fine thread, the fine thread makes the adjustment more precise when rotating the adjusting force sensor 1 and has better self-locking performance.

[0041] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation on the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the above-described technical content to make many possible changes and modifications to the present invention, or modify it into an equivalent embodiment with equivalent variations.
