压力传感器，设置于第一块体16的挤压面或安装腔12的挤压面上，用于在相对应的所述挤压面相互抵紧时检测套体11和第一块体16之间的挤压力。The pressure sensor is arranged on the extrusion surface of the first block 16 or the extrusion surface of the installation cavity 12, and is used to detect the extrusion force between the sleeve body 11 and the first block 16 when the corresponding extrusion surfaces are pressed against each other.
本申请提供的技术方案，可以通过压力传感器检测套体11和第一块体16之间的挤压力，通过挤压力获知钢丝绳的拉力，从而获取作业机械的吊载重量，因此，本申请提供的索节组件不仅能够固定钢丝绳，而且能够实现作业机械的吊载重量检测功能。The technical solution provided by the present application can detect the extrusion force between the sleeve body 11 and the first block 16 through the pressure sensor, and obtain the pulling force of the steel wire rope through the extrusion force, thereby obtaining the hoisting weight of the working machine. Therefore, the socket assembly provided by the present application can not only fix the steel wire rope, but also realize the function of detecting the hoisting weight of the working machine.
下面结合图1-图5详细描述本申请的实施例中的索节组件和作业机械，索节组件包括套体11、第一块体16和压力传感器。The socket assembly and the working machine in the embodiment of the present application will be described in detail below with reference to FIGS. 1-5 . The socket assembly includes a casing 11 , a first block 16 and a pressure sensor.
其中，如图1和图2所示(并参考图5)，套体11设置有安装腔12和固定部，安装腔12为包括大端和小端的楔形腔，楔形腔是指从大端至小端横截面逐渐缩小的腔体，固定部用于与外部装置相连接；在一些实施例中套体11可以为铸造件。如图2所示，图2中安装腔12的上端为小端，下端为大端。沿安装腔12的大端至小端方向，安装腔12的横截面逐渐缩小，以形成楔形结构。安装腔12的大端和小端都可以设置有开口，以供第一块体16和钢丝绳进入。Wherein, as shown in Figure 1 and Figure 2 (with reference to Figure 5), the sleeve body 11 is provided with an installation cavity 12 and a fixed part, the installation cavity 12 is a wedge-shaped cavity including a large end and a small end, the wedge-shaped cavity refers to a cavity gradually reduced in cross section from the large end to the small end, and the fixed part is used to connect with an external device; in some embodiments, the sleeve body 11 can be a casting. As shown in FIG. 2 , the upper end of the installation cavity 12 in FIG. 2 is a small end, and the lower end is a large end. Along the direction from the large end to the small end of the installation cavity 12 , the cross section of the installation cavity 12 is gradually reduced to form a wedge-shaped structure. Both the large end and the small end of the installation cavity 12 can be provided with openings for the first block 16 and the wire rope to enter.
第一块体16用于设置于安装腔12内，第一块体16包括大端和小端，在一个实施例中，第一块体16为包括大端和小端的楔形块，楔形块是指从大端至小端的方向横截面逐渐缩小的块体。第一块体16位于安装腔12内的形状与安装腔12的形状大体一致。在一些实施例中，第一块体16具体可采用铁质材料，第一块体16安装至安装腔12内部，第一块体16的大端至小端方向与安装腔12的大端至小端方向相一致，即，第一块体16的大端靠近安装腔12的大端，第一块体16的小端靠近安装腔12的小端。The first block 16 is used to be arranged in the installation cavity 12. The first block 16 includes a large end and a small end. In one embodiment, the first block 16 is a wedge-shaped block including a large end and a small end. The wedge-shaped block refers to a block whose cross section gradually decreases from the large end to the small end. The shape of the first block 16 located in the installation cavity 12 is substantially consistent with the shape of the installation cavity 12 . In some embodiments, the first block 16 can specifically be made of iron material, the first block 16 is installed inside the installation cavity 12, and the direction from the large end to the small end of the first block 16 is consistent with the direction from the large end to the small end of the installation cavity 12, that is, the large end of the first block 16 is close to the large end of the installation cavity 12, and the small end of the first block 16 is close to the small end of the installation cavity 12.
第一块体16安装至安装腔12内之后，第一块体16和安装腔12之间形成供钢丝绳穿过的间隙，如图4所示，第一块体16的左右两侧和安装腔12的侧壁之间都均有供钢丝绳穿过的间隙，可以将钢丝绳从第一块体16的一侧间隙并绕第一块体16的大端后穿入另一侧的间隙。钢丝绳受拉力时(伸出安装腔12小端的钢丝绳受到从大端朝向小端方向的拉力)，同时钢丝绳施加给第一块体16沿其大端至小端方向的作用力，使第一块体16沿其大端至小端方向运动，在第一块体16的大端逐渐朝向安装腔12的小端运动时，第一块体16和安装腔12之间的间隙逐渐缩小，进而能够进一步夹紧钢丝绳。After the first block 16 is installed in the installation cavity 12, a gap for the wire rope to pass is formed between the first block 16 and the installation cavity 12. As shown in FIG. When the wire rope is under tension (the wire rope protruding from the small end of the installation cavity 12 is subjected to a pulling force from the large end to the small end), the steel wire rope applies force to the first block 16 along the direction from the large end to the small end, so that the first block 16 moves along the direction from the large end to the small end.
第一块体16和安装腔12的内壁设置有相对应的挤压面，即，第一块体16设置有挤压面，安装腔12的内壁也设置有挤压面，且二者的挤压面相对应设置。当钢丝绳穿在第一块体16和安装腔12之间间隙内且受拉力时，第一块体16产生沿其大端至小端方向位移的运动，同时，第一块体16的挤压面与安装腔12的挤压面相互抵紧。The first block 16 and the inner wall of the installation chamber 12 are provided with corresponding extrusion surfaces, that is, the first block 16 is provided with an extrusion surface, and the inner wall of the installation chamber 12 is also provided with an extrusion surface, and the extrusion surfaces of the two are arranged correspondingly. When the steel wire rope passes through the gap between the first block 16 and the installation cavity 12 and is under tension, the first block 16 produces a movement of displacement along the direction from its large end to the small end, and at the same time, the extrusion surface of the first block 16 and the extrusion surface of the installation cavity 12 are pressed against each other.
压力传感器设置于第一块体16的挤压面或安装腔12的挤压面上。当第一块体16的挤压面向安装腔12的挤压面挤紧时，挤压面能够对压力传感器形成挤压，进而压力传感器能够感应第一块体16的压力。The pressure sensor is arranged on the extrusion surface of the first block 16 or the extrusion surface of the installation cavity 12 . When the extrusion surface of the first block 16 is squeezed tightly against the extrusion surface of the installation cavity 12 , the extrusion surface can form a squeeze on the pressure sensor, and then the pressure sensor can sense the pressure of the first block 16 .
如此设置，钢丝绳穿过第一块体16和安装腔12的内壁之间的间隙，由于安装腔12和第一块体16都设置为包括大端和小端的楔形结构，当钢丝绳受拉力时，在钢丝绳的带动作用下，第一块体16产生大端至小端方向的位移，进而进一步将钢丝绳挤紧在第一块体16和安装腔12的内壁之间，实现了钢丝绳的可靠固定。In this way, the steel wire rope passes through the gap between the first block 16 and the inner wall of the installation cavity 12. Since the installation cavity 12 and the first block 16 are both configured as a wedge-shaped structure including a large end and a small end, when the steel wire rope is pulled, the first block 16 is driven by the wire rope.
当钢丝绳受拉力时，第一块体16相对套体11的移动能够使得第一块体16与安装腔12的内壁二者之间的挤压面产生相互抵紧，进而被夹在挤压面之间的压力传感器能够感应到相应的挤压力，压力传感器感应的挤压力与钢丝绳受的拉力相等或呈正相关，进而通过压力传感器能够获取钢丝绳所受到的拉力，钢丝绳受到的拉力与滑轮组的倍率乘积即为吊载重量。When the steel wire rope is under tension, the movement of the first block 16 relative to the sleeve body 11 can make the extrusion surfaces between the first block 16 and the inner wall of the installation cavity 12 press against each other, and then the pressure sensor sandwiched between the extrusion surfaces can sense the corresponding extrusion force.
如此设置，本实施例提供的索节组件，在作业机械吊载物品时，索节组件能够实现检测吊载重量的功能。In this way, the socket assembly provided in this embodiment can realize the function of detecting the lifting weight when the working machine is lifting objects.
在进一步的实施例中，如图1至图3所示，第一块体16设置有第一凸起结构131，安装腔12的内壁设置有第二凸起结构132，第一凸起结构131和第二凸起结构132相对应，第一凸起结构131上形成第一块体16的挤压面，第二凸起结构132上形成安装腔12的内壁上的挤压面。In a further embodiment, as shown in FIGS. 1 to 3 , the first block 16 is provided with a first protruding structure 131 , and the inner wall of the mounting cavity 12 is provided with a second protruding structure 132 , the first protruding structure 131 corresponds to the second protruding structure 132 , the first protruding structure 131 forms a pressing surface of the first block 16 , and the second protruding structure 132 forms an extruding surface on the inner wall of the mounting cavity 12 .
在一些实施例中，第一凸起结构131和第二凸起结构132分别凸起于第一块体16和安装腔12的内壁，第一凸起结构131和第二凸起结构132可以通过铸造方式分别与第一块体16和安装腔12的内壁形成一体式结构，第一凸起结构131和第二凸起结构132对应形成的挤压面可以设置为平面，压力传感器可通过焊接、螺钉连接等方式连接在挤压面上。In some embodiments, the first protruding structure 131 and the second protruding structure 132 respectively protrude from the inner wall of the first block 16 and the installation cavity 12, and the first protruding structure 131 and the second protruding structure 132 can respectively form an integrated structure with the inner wall of the first block 16 and the installation cavity 12 by casting.
其中，为使得第一凸起结构131和第二凸起结构132能够在第一块体16相对套体11移动时能够逐渐相互挤紧，第一凸起结构131和第二凸起结构132中的一者设置为挤压面逐渐升起的楔形块。Wherein, in order to enable the first protruding structure 131 and the second protruding structure 132 to be able to squeeze each other gradually when the first block 16 moves relative to the casing 11, one of the first protruding structure 131 and the second protruding structure 132 is set as a wedge-shaped block whose extrusion surface gradually rises.
在进一步的实施例中，第一块体16的两侧都设置有第一凸起结构131，安装腔12的内壁上的第二凸起结构132与第一楔形块上的第一凸起结构131一一对应。当第一块体16在钢丝绳的带动作用下，第一块体16两侧的第一凸起结构131同时与安装腔12的内壁上的第二凸起结构132产生挤压作用，第一块体16的两侧受力平衡，避免了第一块体16发生偏斜，导致钢丝绳不能被有效固定的问题。In a further embodiment, both sides of the first block 16 are provided with first protruding structures 131 , and the second protruding structures 132 on the inner wall of the installation cavity 12 correspond to the first protruding structures 131 on the first wedge block. When the first block 16 is driven by the wire rope, the first protruding structures 131 on both sides of the first block 16 will simultaneously press against the second protruding structure 132 on the inner wall of the installation cavity 12, and the forces on both sides of the first block 16 will be balanced, avoiding the deflection of the first block 16, resulting in the problem that the wire rope cannot be effectively fixed.
在进一步的实施例中，套体11上设置有高度检测装置，高度检测装置用于检测距离地面的高度。在一些实施例中，高度检测装置可以包括微波发射单元20和微波接收单元21，如图5所示的实施例中，微波发射单元20和微波接收单元21均安装在套体11上。微波发射单元20用于朝地面发射微波，微波接收单元21用于接收地面反射回的微波，高度检测装置根据发射微波和接收微波的时间差能够确定出距离地面的高度。例如，微波发射单元20在第一时间点发射 微波，微波接收单元21在第二时间点接收微波，根据第二时间点和第二时间点的时间差以及微波传播速度即可以计算出距离地面的高度。In a further embodiment, the sleeve body 11 is provided with a height detection device for detecting the height from the ground. In some embodiments, the height detection device may include a microwave transmitting unit 20 and a microwave receiving unit 21 . In the embodiment shown in FIG. 5 , the microwave transmitting unit 20 and the microwave receiving unit 21 are both installed on the casing 11 . The microwave transmitting unit 20 is used to transmit microwaves toward the ground, and the microwave receiving unit 21 is used to receive microwaves reflected from the ground. The height detection device can determine the height from the ground according to the time difference between transmitting microwaves and receiving microwaves. For example, the microwave transmitting unit 20 transmits microwaves at the first time point, and the microwave receiving unit 21 receives microwaves at the second time point, and the height from the ground can be calculated according to the time difference between the second time point and the second time point and the microwave propagation speed.
另外，在进一步的实施例中，索节组件还可以包括信号发射装置，信号发射装置与压力传感器和高度检测装置电连接，信号发射装置用于发射压力传感器采集的压力信号，以及高度检测装置检测的高度信号。压力传感器和高度检测装置采集的信息，通过信号发射装置发送至作业机械的主控机上，经过主控机处理后的吊载数据和高度数据可通过显示屏显示出来。In addition, in a further embodiment, the socket assembly may further include a signal emitting device, the signal emitting device is electrically connected to the pressure sensor and the height detecting device, and the signal emitting device is used to transmit the pressure signal collected by the pressure sensor and the height signal detected by the height detecting device. The information collected by the pressure sensor and the height detection device is sent to the main control computer of the working machine through the signal transmitting device, and the hoisting data and height data processed by the main control computer can be displayed on the display screen.
在一些实施例中，索节组件的第一块体16设置有绳槽17，如图3所示，绳槽17沿第一块体16的周向延伸，绳槽17的横截面可以为弧形，以便与钢丝绳能够平滑接触，避免损伤钢丝绳。绳槽17的深度小于钢丝绳的直径，以使钢丝绳局部露出绳槽17，使得钢丝绳能够被挤压。In some embodiments, the first block 16 of the socket assembly is provided with a rope groove 17. As shown in FIG. 3 , the rope groove 17 extends along the circumference of the first block 16, and the cross section of the rope groove 17 can be arc-shaped, so as to be in smooth contact with the wire rope and avoid damage to the wire rope. The depth of the rope groove 17 is smaller than the diameter of the steel wire rope, so that the steel wire rope partially exposes the rope groove 17, so that the steel wire rope can be squeezed.
需要说明的是，固定钢丝绳时，钢丝绳沿第一块体16的周向环绕在第一块体16上之后，再将第一块体16卡紧在套体11内，钢丝绳被挤紧在第一块体16和安装腔12的内壁之间。鉴于此，在进一步的实施例中，第一块体16的大端和小端都设置为弧形结构。It should be noted that when fixing the steel wire rope, after the steel wire rope wraps around the first block 16 along the circumference of the first block 16, the first block 16 is clamped in the casing 11, and the steel wire is squeezed between the first block 16 and the inner wall of the installation cavity 12. In view of this, in a further embodiment, both the large end and the small end of the first block 16 are arranged in an arc-shaped structure.
如此设置，钢丝绳环绕在第一块体16上时，钢丝绳不会出现直角弯折的情况，避免钢丝绳的损伤。With such arrangement, when the steel wire rope is wound around the first block 16, the steel wire rope will not be bent at a right angle to avoid damage to the steel wire rope.
为了进一步提高钢丝绳的稳定性，在进一步的实施例中，索节组件还可以包括第二块体18，第二块体18用于***于套体11内，且第二块体18与第一块体16相抵紧，即如图4和图5所示，第二块体18用于***于第一块体16与套体11之间，第二块体18与第一块体16之间设置有供钢丝绳通过的间隙，在第一块体16相对于套体11移动时第二块体18和第一块体16夹紧钢丝绳。In order to further improve the stability of the wire rope, in a further embodiment, the socket assembly can also include a second block 18, the second block 18 is used to be inserted into the sleeve body 11, and the second block 18 is pressed against the first block 16, that is, as shown in Figures 4 and 5, the second block 18 is used to be inserted between the first block 16 and the sleeve 11. The block 18 and the first block 16 clamp the wire rope.
第二块体18***于套体11内，在套体11的约束作用下，第二块体18能够与第一块体16相抵，并且第二块体18也为具有大端和小端的楔形块，钢丝绳受拉力时，第二块体18具有沿其大端至小端方向运动的趋势，进而能够进一步将钢丝绳夹紧，进一步提高了钢丝绳的稳定性。The second block 18 is inserted in the sleeve 11. Under the constraints of the sleeve 11, the second block 18 can be offset against the first block 16, and the second block 18 is also a wedge-shaped block with a large end and a small end. When the steel wire rope is pulled, the second block 18 has a tendency to move along the direction from the large end to the small end, so that the steel wire rope can be further clamped, and the stability of the steel wire rope is further improved.
第二块体18与钢丝绳相接触的一侧也可设置有用于容纳钢丝绳的槽结构，第二块体18的槽结构与第一块体16的绳槽17相对应，第二块体18和第一块体16抵紧时，能够将钢丝绳夹紧在第一块体16和第二块体18之间的绳槽内。The side where the second block 18 is in contact with the wire rope can also be provided with a groove structure for accommodating the wire rope. The groove structure of the second block 18 corresponds to the rope groove 17 of the first block 16. When the second block 18 and the first block 16 are pressed together, the wire rope can be clamped in the rope groove between the first block 16 and the second block 18.
在一些实施例中，索节组件可以连接在吊钩组件上，当钢丝绳绕过吊钩组件的动滑轮组之后，钢丝绳的端部通过索节组件固定在吊钩组件上。In some embodiments, the socket assembly can be connected to the hook assembly, and after the steel wire rope passes around the movable pulley block of the hook assembly, the end of the wire rope is fixed on the hook assembly through the socket assembly.

当然，在其它实施例中，套体11的固定部也可通过焊接、螺栓连接等方式连接在吊钩组件或臂架上。Of course, in other embodiments, the fixing part of the sleeve body 11 may also be connected to the hook assembly or the jib by means of welding, bolting or the like.
