Description
技术领域
本实用新型涉及输砂设备技术领域,更具体地说,涉及一种输砂半挂车。
背景技术
随着油田增产压裂用砂量的增加,对压裂用砂的运输和储存效率提出了更高的要求。
对于页岩气、致密油气的开发,水平分段压裂是核心关键技术,随着国内水平分段压裂技术的引进和推广,大规模输砂设备成为油田作业的需求,而国内没有相应的设备。
但是,为了适应大输砂量而使用的大型输砂设备中,对于输砂量误差较大,无法精确控制输砂量,造成了不必要的浪费。
综上所述,如何提供一种输砂半挂车,以精确控制输砂量,是目前本领域技术人员亟待解决的问题。
实用新型内容
有鉴于此,本实用新型提供了一种输砂半挂车,以精确控制输砂量。
为了达到上述目的,本实用新型提供如下技术方案:
一种输砂半挂车,包括输砂机架及设置于所述输砂机架上的输送皮带,
所述输砂机架上设置有称重装置,所述称重装置与所述输送皮带接触。
优选地,上述输砂半挂车中,所述输砂机架包括倾斜机架及与所述倾斜机架连接的水平机架;
所述称重装置设置于所述倾斜机架上。
优选地,上述输砂半挂车中,所述称重装置包括:
与所述输砂机架固定连接的称重秤;
设置于所述称重秤与所述输送皮带之间的重力传递装置。
优选地,上述输砂半挂车中,所述重力传递装置包括固定设置于所述称重秤上的固定支架及与所述固定支架转动连接的托辊,所述托辊与所述输送皮带的上皮带相抵。
优选地,上述输砂半挂车中,所述固定支架与所述称重秤螺栓连接。
优选地,上述输砂半挂车中,还包括设置于所述重力传递装置后方的皮带支撑架,所述皮带支撑架具有支撑所述输送皮带的支撑端。
优选地,上述输砂半挂车中,所述皮带支撑架与所述输砂机架固定连接。
优选地,上述输砂半挂车中,所述称重秤为累计秤。
本实用新型提供的输砂半挂车,在输砂机架上设置有称重装置,由于称重装置与输送皮带接触,可以将输送皮带及其上砂粒的重量进行称重,并根据称重装置的称重结果得出输送皮带的瞬时输砂量,并且,在计时装置的辅助下,得出单位时间的输砂量,进而达到精确控制输砂量的效果。
附图说明
为了更清楚地说明本实用新型实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本实用新型的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。
图1为本实用新型实施例提供的输砂半挂车的结构示意图;
图2为图1中A部分的局部放大示意图。
其中,
称重秤—1,皮带支撑架—2,输送皮带—3,托辊—4,倾斜机架—E,水平机架—F。
具体实施方式
本实用新型提供了一种输砂半挂车,以精确控制输砂量。
请参考图1和图2,图1为本实用新型实施例提供的输砂半挂车的结构示意图;图2为图1中A部分的局部放大示意图。
本实用新型实施例提供了一种输砂半挂车,包括输砂机架及设置于输砂机架上的输送皮带3,输砂机架上设置有称重装置,称重装置与输送皮带3接触。
本实用新型实施例提供的输砂半挂车,在输砂机架上设置有称重装置,由于称重装置与输送皮带3接触,可以将输送皮带3及其上砂粒的重量进行称重,并根据称重装置的称重结果得出输送皮带3的瞬时输砂量,并且,在计时装置的辅助下,得出单位时间的输砂量,进而达到精确控制输砂量的效果。
其中,计时装置可以为称重装置内置的计时单元,也可以为外置的时间计算器,如秒表或计时器等。
在砂粒运输过程中,不可避免的会存在砂粒由传输带泄漏的情况。在本实施例中,输砂机架包括倾斜机架E及与倾斜机架E连接的水平机架F;在砂粒传递过程中,砂粒在输送皮带3的带动下由水平机架F向倾斜机架E运动。为了进一步优化对输砂半挂车的输送量的控制,称重装置设置于倾斜机架E上。即,称重装置设置于本实用新型实施例提供的输砂半挂车靠近输出端的倾斜机架E上,进而避免因输送砂粒过程中砂粒泄漏而影响的输砂量的精确度。
也可以将称重装置设置于水平机架F上,以达到同样的技术效果,在此不再详细介绍。
如图2所示,本实用新型实施例提供的输砂半挂车中,称重装置包括:与输砂机架固定连接的称重秤1;设置于称重秤1与输送皮带3之间的重力传递装置。通过重力传递装置将其与输送皮带3接触位置的重力传递给称重秤1,提高称重精确性。在本实施例中,称重秤1固定设置于倾斜机架E上,其与倾斜机架E通过螺栓连接,以便于称重秤1的更换及维修。
由于输送皮带3相对于输砂机架转动,而重力传递装置相对于输砂机架固定,即,在称重过程中,输送皮带3与重力传递装置之间发生摩擦。为了减少输送皮带3与重力传递装置之间的摩擦以提高两者的使用寿命,重力传递装置包括固定设置于称重秤1上的固定支架及与固定支架转动连接的托辊4,托辊4与输送皮带3的上皮带相抵。托辊4与输送皮带3的上皮带相抵,在输送皮带3的输送过程中,托辊4相对于固定支架转动,使得托辊4与输送皮带3之间的摩擦力较小,进而提高装置使用寿命。
其中,需要说明的是,输送皮带3的上皮带为输送皮带3输送砂粒的部分。
优选地,固定支架与称重秤1螺栓连接。以便于重力传递装置与称重秤1的拆卸安装。方便了称重装置向输砂机架的安装。
进一步地,本实用新型实施例提供的输砂半挂车还包括设置于重力传递装置后方的皮带支撑架2,皮带支撑架2具有支撑输送皮带3的支撑端。通过皮带支撑架2的支撑端对输送皮带3的支撑,使得输送皮带3平稳运行。其中,重力传递装置后方由输送皮带3输送砂粒的方向而定,即输送皮带3输送的砂粒先经过重力传递装置进行称重,并由皮带支撑架2的支撑端支撑,在输送皮带3上稳定输送。
皮带支撑架2与输砂机架固定连接。即,在本实施例中,皮带支撑架2与倾斜机架E固定连接。也可以将皮带支撑架2固定设置于称重秤1上,进而简化安装过程。
进一步地,秤重秤1优选为累计秤,即秤重秤1可获得累计秤重量,便于称重由本实用新型实施例提供的输砂半挂车输送的砂粒的总重量,使砂粒总重量作为压裂作业的操作参考。
对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本实用新型。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本实用新型的精神或范围的情况下,在其它实施例中实现。因此,本实用新型将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
